        string(2266) "Recent years have seen renewed interest and increase in efforts directed towards development of technology for high-frequency (microwave and beyond) and high-speed superconducting and cryogenic electronics systems. The discovery of superconductivity is recognized as an IEEE Milestone in Electrical and Computer Engineering and has made possible many important applications across a wide range of disciplines. Cryogenic electronics holds the promise of high performance and super-low energy per operation for computing applications that can take us beyond the end of the semiconducting technology roadmap. Driven by goals of ultra-high speed computing and signal processing, super-sharp and low-loss filters, higher performance MRI/NMR systems and integration with computing or imaging systems that must be cryogenically cooled due to noise constraints, there is a growing interest in active and passive microwave components designed for operation at low temperatures. Historically, despite the potential of higher performance from cryogenic components and systems, conventional technologies have provided sufficient performance. There are, however, reasons to believe that this situation may change in the near future. As one example, consider the case of superconducting quantum computing, where communication between qubits occurs through signals in the microwave regime and where the noise constraints are of utmost importance. Proper communication, control and integration of systems such as this will require superconducting and cryogenic microwave technology advancements that are now in development. This workshop aims to provide a sufficiently detailed description and platform for discussion of the current status and future of superconducting and semiconducting electronics for cryogenic systems. Talks in this workshop will cover: RF MEMS + superconducting filters, HTS filters, superconducting filters for resonance imaging systems, advances in superconducting microwave technology in Japan and China, superconducting microwave interconnect technology, recent superconducting device technology developments for mixed-signal circuits, recent cryogenic semiconducting device technology developments and cryogenic electronics for quantum computing systems."

            string(1665) "Superconducting digital technology has made rapid strides in recent years. Energy-efficient single flux quantum (SFQ) circuits have been proposed so far and complicated circuits like a microprocessor have been demonstrated at several tens of GHz. For example, our group successfully demonstrated 100 GHz operation of a bit-serial microprocessor based on the multiple-voltage SFQ (MV-SFQ) circuit. In addition, we designed a RISC-based MV-SFQ microprocessor with an embedded instruction and data memory, and confirmed execution of all the instructions stored in the instruction memory. Note that these circuits are designed based on the SFQ-specific CAD tools in a digital domain and sometimes based on a microwave simulator for analog components. Furthermore, the introduction of ferromagnetic materials to devices or circuits, the invention of superconducting nano-devices, and the combination with CMOS integrated circuits enhance flexibility of the analog circuits as well as digital circuits and lead to technological innovation. Almost all the remaining issues such as large capacity memories, rectifiers, will be overcome by using these technologies. Superconducting digital technology is now transformed into cryogenic digital technology. Although the above-mentioned technologies are based on Nb or NbN films, I will give some comments on the importance of high-temperature-superconductor (HTS) films. In fact, the waveguides made of HTS films are essential for, broadband communications with ultra-low heat inflow between a 1st stage and a 2nd stage of a cryocooler. HTS analog active nanodevices would be attractive for an amplifier operating around 50 K."

            string(1884) "Superconductor integrated circuits (ICs), built with niobium Josephson junctions (JJs), offer an attractive combination of features for mixed-signal electronics up to frequencies above 100 GHz. In these circuits, conversion between analog and digital domains can be done with high fidelity, by exploiting magnetic flux quantization, and at high speed. Niobium JJs have picosecond switching times and enable sampling rates above 100 GHz. This fast and accurate analog-to-digital conversion function is strengthened by the ability to integrate ultrafast, low-power digital circuits and low-loss analog circuits on the same chip. These features give rise to a class of mixed-signal circuits for a diversity of applications, ranging from communications to quantum computing. Among these are software radio and digital radar applications which benefit from digital signal processing applied directly on digitized radio frequency (RF) waveforms. On the other hand, the same technology applies to reading out cryogenic detectors and qubits. In this paper, we describe the current state-of-the-art of digital-RF systems, featuring superconductor mixed-signal circuits. The latest generation of these robust cryocooled systems are modular and have been operated for a variety of applications over the last four years. In these systems, the function of superconductor mixed-signal ICs is augmented by semiconductor cryogenic and room-temperature electronics. We also describe the next generation of superconductor ICs that are faster and feature much higher integration density and complexity. Finally, microwave design challenges will be discussed in two critical areas: (1) interchip interconnects for analog signals and picosecond-wide single flux quantum (SFQ) pulses supporting rates above 100 GHz , and (2) generation, distribution and synchronization of clock signals also above 100 GHz."

            string(3894) "In recent years, great efforts have been devoted to the research and development of high temperature superconducting (HTS) filters in China. Novel HTS filter design technologies were well developed including those in coupling matrix extraction, wide stop band realization, liner phase, multiplexer, multi-band and multi-mode designs, and frequency tunable filters. Based on these techniques, high performance HTS filters were constructed and excellent specifications were achieved, e.g., 0.05 dB minimum insertion loss, -23 dB return loss, -110 dB out-of-band rejection and 220 dB/MHz band-edge slope, etc., which are among the best results in the literatures. Applications of HTS filters are also successful. A demonstration wireless communication cluster with HTS filter subsystems was built in the urban area of Beijing. Each base transceiver station (BTS) was installed with an HTS filter subsystem consisting of six HTS filters with the same performance. The measurement results show a 2.35 dB decrease of mobile phone mean transmit power when the normal filter subsystems were replaced by HTS filter subsystems. Based on the success in constructing an HTS filter handling high power up to 11.7 W, one of the highest records in the literature, the world first HTS transceiver was constructed, which was installed in a 3rd generation TD-SCDMA base station (it works in TDD mode, i.e., the receiving and emitting signals use the same frequency channel). Field trial in commercial network showed excellent improvements in reducing bit error (80%), enhancing anti-interference (10 dBm), restricting spurious power in emitting signals (26 dBm), and also in receiving quality of video communications. Field trial for the 4th generation mobile communication systems (e.g. TD-LTE) is now being carried out and results will be reported in the symposium. Another interesting application is to radar system, e.g., the meteorological radar, which is sometimes paralyzed by heavy electromagnetic interference in urban area due to the lack of extremely narrow bandwidth pre-selective filters. Laboratory tests proved that, with HTS subsystem, improvements of sensitivity (3.8 dB) and interference rejection (48.4 dB) have been achieved. A demonstration HTS meteorological radar station was then set up in Beijing. Comparison measurements showed that due to interference, the conventional wind profiler could not attain stable and reliable wind profiles above 1500m where the echoes are weak. In contrast, the HTS wind profiler provided complete and coincident wind profiles up to 3500 m. In poor weather conditions or severe electromagnetic environment, the conventional wind profiler almost stopped working, while the HTS wind profiler functioned well, and complete wind profile data on both the time scale and the spatial scale could be obtained by using the HTS wind profiler. The third application is to radio astronomy and deep space detection. HTS filters were deployed in the ground stations of Chinese lunar exploration project, which played an important role in monitoring the mission of Chang'e No. 3 satellite. Finally, applications in space technology are most challenging and attractive. In 2005, the first ground test system showed that a reduction of 73% in noise temperature was obtained by substituting HTS front-end for its conventional counterpart. On October 14, 2012, the HTS experimental system was successfully launched into orbit as a payload of a civil experimental satellite for new technologies (Practice No 9). The received on-orbit experimental data showed that the HTS system worked perfect in the past years. This is the world second successful space experiment for HTS devices after the American’s HTSSE. Application of HTS filter front-end in a space science project is also ready for space mission with Chinese Space Laboratory, to be launched in mid September, 2016."

In such applications, it is necessary to create a thin film with a low microwave surface resistance (Rs) under a high magnetic field. The introduction of artificial pins (Aps) in YBa2Cu3O7 (YBCO) thin film is useful to reduce the Rs in high magnetic fields. We examined the formation of APS by ion implantation of Si, Mo and In ions. We found that Rs of ion-implanted YBCO thin films could be reduced to about one-quarter of the non-irradiated YBCO thin films. We also examined the APs structure by positron annihilation life time spectroscopy. As a result APs was found to be a vacancy of about 0.5nm3. We developed a prototype 700MHzNMR pickup coil made by YBCO thin films. The sensitivity of NMR could be improved by using YBCO pickup coil compared with using a conventional NMR pickup coil. It is expected to improve further sensitivity by using the ion-implanted YBCO thin film, and we are currently considering it."

These transmitters include up-conversion, filtering and output power amplifier stages. They are capable of generating ~1 W of output power with very good total system efficiency. Furthermore, they provide flexibility for software defined systems that allow quick re-configuration via software programming. Additionally, they are compact, often requiring areas less than 1mm2. In this workshop we will examine three main types of digital transmitters: outphasing based pulse-width modulation, switched-capacitor power amplifiers and current-mode digital power amplifiers. Additionally, there are many different architectures that utilize each of the above topologies, including class-G, polar, outphasing and multiphase. The presenters will provide examples of these architectures and provide insight into their designs and the scenarios in which their use is optimal."

On the other hand, innovations in analog circuits have been driven by rapidly evolving semiconductor technology in line with Moore’s law. A switched capacitor power amplification (SCPA) technique, based on RF switched capacitor digital-to-analog converter architecture, offers very high energy efficiency and superior linearity for wireless transmitters. The measured peak Pout and power-added-efficiency (PAE) of a prototype SCPA are 25.2 dBm and 45%, respectively. For 802.11g 64-QAM OFDM modulated signal, the average Pout and PAE are 17.7 dBm and 27%, respectively, and the measured EVM is 2.6%. Class-G technique can be applied to SCPA to further enhance the efficiency. With additional supply voltage and advanced switching scheme for multiple supply voltages, the measured peak Pout and PAE are 24.3 dBm and 43.5%, respectively, whereas the average Pout and PAE are 16.8 dBm and 33%, respectively, for 802.11g signals.

A three-level LO clock is employed to improve the digitizing efficiency and to combine I and Q signals in time domain. Since the signals are in a single stream, I and Q signals could be up-converted using the one sampling mixer, realizing I/Q sharing structure. The mixer thermo-code element pairs whose output powers are internally cancelled, are disabled to reduce the power consumption. The resulting RFDAC provides the efficiency comparable to the polar transmitter without using a Cordic. The output powers of the mixer elements are amplified by inverters and the final powers of the cells are combined using a capacitor array similarly to the switched capacitor DAC. To reduce the thermo-code elements, the data is processed only in the first quadrant and is rotated to the original position. A dual Vdd structure is also employed. The detailed design issues and the measured performances of the transmitter will be discussed."

I will introduce several techniques that implement SCPAs in discrete phase spaces; several multiple phase digital PA architectures will be discussed that alleviate the need for wideband phase modulators and synchronization.

The digitally intensive and reprogrammable nature of RF power DACs opens the door to creating hybrid and broadband power amplifier architectures that can combine the advantages of different power amplifier techniques and potentially achieve superior peak power efficiency, back-off efficiency, and linearity. These hybrid architectures cannot be easily realized using conventional analog power amplifiers. Two power amplifier design will be presented as examples of such hybrid digitally intensive power amplifiers. One design exploits the real-time cooperation of dynamic load modulation and class-G supply modulation, and the other design shows a power amplifier with broadband and highly linear operation."

Hence an architecture that can benefit truly from technology scaling as well as offer wideband multi-mode performance will be beneficial. Such architecture is indispensable for reconfigurable or software-defined radios. Digitally modulated transmitters offer such a solution. In this talk, we will cover the pros and cons of a digitally modulated transmitter with special emphasis on a power amplifier. Ways of achieving higher efficiency by using novel impedance modulation will be introduced.

PWM offers an efficient approach for implementing transmitters. The approach is especially well-suited for digitally-intensive, CMOS-friendly implementations.  While PWM combined with a class-D output stage has been very effectively employed in audio systems, its use in 
wider bandwidth applications such as wireless systems requires an exploration of new circuit techniques and architectures.

In this talk, we will describe PWM-based transmitter architectures for applications where the signal bandwidth can extend from several hundreds of KHz to tens of MHz.   Transmitters that allow for PWM generation at RF, without the requirement for frequency upconversion, will be 
described. An overview of the benefits and potential limitations of the PWM approach will be presented. Practical implementations of wireless transmitters employing this approach will also be presented."

            string(1609) "The first published THz medical imaging appeared in the literature at the end of the 1990s and the field experienced accelerated research and development well into the 2000s. The vast majority of reported systems were THz time domain spectroscopy (TDS) and THz time domain imaging (TDI) where ultra-broadband pulses with typically > 1 THz of instantaneous bandwidth were generated and synchronously detected with some combination of photoconductive and electro-optic devices driven by femtosecond lasers. 
Fast forward to today and while much progress has been made in clinically relevant investigations, clinical translation of THz technology has been limited. There are many applications where TDS and/or TDI still seem ideally suited. However, there is growing evidence that THz imaging systems based on RF technology (part of the standard tool set in the fields of personnel imaging, non-destructive evaluation, and radio astronomy) may be well matched for a multitude of clinical investigations. These issues strongly suggest broad instantaneous bandwidth may not be necessary and thus that the field of THz medical imaging may benefit greatly from research and development of systems based on RF technology.
In this talk we introduce two medical applications where video rate acquisition of large areas of the body in pursuit of high contrast anomaly detection would immediately generate interest from the medical community. Further, physiologic and clinical work flow arguments will be made that highlight some of the limitations of TDS/TDI and emphasize the unique capabilities of RF based systems."

Techniques presented include on-chip antennas, artificial magnetic conductors, diode-based mixers, and high-precision PLLs. Full spectroscopy measurements using these CMOS components will also be reported.
200-250-GHz transmitter and receiver for rotational spectroscopy, which can identify a wide variety of molecules in gas phase and quantify their concentration are demonstrated in 65-nm CMOS. Because the width of spectral lines is ~1MHz or Q is more than 200,000, lines of different molecules do not overlap and provide almost absolute specificity. A rotational spectrometer is an electronic nose. Considering how smell is used in daily life, the number of applications should be almost limitless.

In this review, the authors describe the techniques in its various implementations for static and time-resolved spectroscopy and imaging, and illustrate the performance of the technique with recent examples with various laboratory and industrial projects. Possible future improvements are related to semiconductor or optical laser sources and detector (Quantum Cascade laser and MMIC sources and sensors, THz camera for example).

            string(1304) "The performance of a differential LC oscillator can be enhanced by resonating the common-mode of the circuit at twice the oscillation frequency. When this technique is correctly employed, Q-degradation due to the triode operation of the differential pair is eliminated and flicker noise is nulled. Although the original topology using this technique first appeared in 2001, its performance remains state of the art.

In this workshop, we will use Bank’s general result to show that common-mode resonate topologies are, in fact, near-optimal. That is, for a given resonator tank Q, the FOM of such a design is within 1dB of theoretical limit for any oscillator. Common design pitfalls, which may prevent this near optimal behavior, will be explained and the importance of differential pair sizing will be explored. Insights from class-D and class-C topologies will be used to gain additional intuition into the optimization of the differential pair.

It will also be shown how recently published topologies achieve common-mode resonance using a single differential LC tank (i.e. removing the requirement for an additional tail inductor). Although such topologies have one less degree of design freedom, their performance is theoretical identically to the standard approach of using a tail resonate tank."

            string(2010) "Spectral purity of RF LC-tank oscillators is typically addressed by enhancing its oscilla-tion voltage, improving the quality factor of the tank, lowering its noise factor, and in-creasing its power consumption. 
However, the rate of improvement in phase noise versus power consumption reduces as the core devices enter the triode region. On the other hand, technology scaling limits the oscillation voltage swing due to the reliability issues. It also slightly degrades the tank Q-factor and transistor excess noise factor and thus penalizing oscillator phase noise. Conse-quently, the oscillators of excellent spectral purity and power efficiency are becoming more and more challenging. This has motivated an intensive research leading to recently introduced new oscillator topologies. In the first part of this presentation, we specifically address the ultra-low phase noise design space while maintaining high power efficiency. The main idea is to enforce a pseudo-square or clipped voltage waveform around the LC-tank by increasing the second or/and third harmonics of the fundamental oscillation volt-age through additional impedance peaks, thus giving rise to a class-F operation. 
As a result, the oscillator impulse sensitivity function and circuit-to-phase noise conver-sion reduce especially when the active gm-devices periodically enter the triode region during which the LC-tank is heavily loaded. 
In the second part of this talk, we switch gears to the ultra-low voltage and power design space for Internet-of-Things (IoT) applications. The benefits and constraints of different flavors of LC oscillators are investigated from this perspective. It will be shown that a switching current-source oscillator combines advantages of low supply voltage of the conventional NMOS cross-coupled oscillator with high current efficiency of the comple-mentary push-pull oscillator to reduce the oscillator supply voltage and dissipated power further than practically possible in the traditional oscillators."

The design challenges related to achieving minimum phase noise for a given set of technology parameters (supply voltage, metal stack, varactor devices, etc.) will be discussed with particular emphasis to attaining low phase noise while using varactor diodes, to the use of magnetic transformers in the resonator, and to the selection of the most appropriate oscillator topology. Suitable design techniques to tackle such issues will be illustrated. As a design example of the use of the proposed techniques, two class-C VCOs tailored for operation in the K-band will be presented."

            string(1528) "Modern mobile communication systems need clocks with very low phase noise and low power consumption. In RF and mm-wave oscillators this can be achieved acting on the oscillator topology and/or on the resonator quality factor. Oscillator topology affects the power vs phase noise trade-off in two equally important ways. First, acting on the conversion of circuit noise into phase noise through changing the impulse sensitivity function (ISF); second, changing the maximum achievable power conversion efficiency, i.e. the conversion of DC power into resonator RF power, which directly affects the phase noise. The goal of this talk is to investigate the ultimate performance limit for some of the most used oscillators topologies, including most types of class-B (standard, AC-coupled and with tail filter), class-C and class-F LC oscillators as well as mm-wave distributed oscillators (traveling-wave and standing-wave). An intuitive yet sufficiently accurate formulation of phase noise is presented. To compare different topologies an excess noise factor that represents the difference between the maximum achievable Figure of Merit and the actual one is also introduced. In addition, the theory is experimentally verified in a rigorous and objective way comparing different topologies in the exact same operating conditions, i.e. technology, Q of the tank, dividers, etc. Measurements on several chip prototypes allow to verify, in an unbiased way a very good agreement between the model and both simulations and measurements."

However, several interesting challenges in the mm-wave space, especially close to the fT/fmax, motivate the need for a closer examination of the tuning range and phase noise in mm-wave VCOs. This seminar will elucidate some of the key challenges in designing mm-wave VCOs while also offering some insight on how to design them “robustly” in silicon-based technologies. First a detailed analysis of the ultimate performance bounds in simultaneously achieving low phase noise and wide tuning range will be presented. Next, the impact of technology scaling on the achievable performance bounds will be illustrated. The tuning range and close-in/far-out phase noise performance of MOS and HBT VCOs across the 10-70 GHz space will then be analyzed and compared. Here, special attention will be paid to the impact of different circuit parameters on the phase noise performance in both VCOs. Finally, a new BiCMOS topology is elicited and demonstrated to meet stringent phase noise and turning   range specifications."

        string(1780) "The decade of frequency spectrum spanning 100 GHz to 1000 GHz has promised a plethora of novel applications ranging from communication to sensing, spectroscopy and high-resolution imaging. The spectrum has been successful in attracting rapt attention (and controversies in perhaps equal measure) from scientists and engineers who have been dedicated to finding the killer application with the right technology for many years. However, it is only in the last decade, that we have seen unprecedented improvement in the technology space that has allowed early demonstrations of fully integrated complex systems at these frequencies including chip-scale and wafer-scale phased arrays, multi-GB/s communication systems, imaging and spectroscopy, to name a few. Not surprisingly, at the intersection between microwave and infra-red frequencies, the underlying technology space also spans from solid-state devices (III-V, silicon, hybrid etc) to photonics-based approaches. Now that we are closer than ever before to a potentially diverse set of technology that can successfully address the spectrum, it is time to look into the future to gauge the prospects that lie ahead and ask fundamental questions: What are the unique opportunities in this frequency range and what is the right technology? Is this evolving spectral space comparable to what mm-Wave (below 100 GHz) was a decade ago? Are there unique design methodologies and paradigms cutting across the various layers of abstraction that can break the classical trade-offs in efficiency and scalability. In this workshop, we bring experts working across the technology space to understand the challenges and discuss these fundamental opportunities that can open up the spectrum for transformative technology in the coming decade."

and communication beyond the niche scientific applications that the spectrum is currently known for. While this is partially facilitated by scaling that has pushed device cut-off frequencies (ft, fmax) up into the higher mm-Wave and THz frequency range, the true paradigm shift in silicon integration is that it provides a unique opportunity to enable a new field of active THz electromagnetics realizable through a circuits-EM-systems codesign approach. At these frequencies, the chip dimension is several times larger than the THz wavelengths which allows novel scattering and radiating properties in a substrate that simultaneously supports a billion high-frequency transistors that can generate, process and sense these signals. The ability to actively synthesize, manipulate and sense THz EM fields at subwavelength scales with circuits opens up a new design space for THz electronics. THz architectures emerging from this space are often multi-functional, reconfigurable and break many of the classical trade-offs of a partitioned design approach. This talk will provide examples to illustrate this design methodology on THz signal generation with beam-forming and spectrum control and THz spectrum sensing."

            string(2732) "Terahertz circuits, interconnects, and packaging have received unprecedented attention in recent years for their use in emerging areas such as security screening and standoff weapons detection, high speed digital communications, automatic landing systems through fog and dust, and even for aircraft re-fueling in air. Traditional terahertz application areas such as high-resolution spectrometers and imagers for astrophysics, planetary, and Earth science instruments are increasingly looking for multi-pixel array architecture which requires high level of integration and packaging. Active components such as InP high electron mobility transistors (HEMT) and metamorhpic HEMT (mHEMT), heterojunction bipolar transistors (HBT), GaAs Schottky diodes, and CMOS circuits are being used at these frequencies. However, one major challenge has been to integrate them in a multipixel
detector system with low-loss interconnects and build a highly integrated package.

Common interconnect circuits such as microstrips and CPW lines are too lossy at these frequencies. Moreover, conventional approach of building single-pixel receivers and stacking them to assemble multi-pixel array receivers is not suited at terahertz frequencies. What one needs are novel ultra-compact receiver architectures which are easy to fabricate, preferably by lithographic techniques, to build multi-pixel array receivers where majority of the front-end components along with the antenna element can be integrated in a small form factor. In this workshop presentation we’ll talk about different multi-pixel receiver architectures at terahertz frequencies, specifically focusing on silicon micro-machined front-end components. We’ll discuss novel stacking of micro-machined silicon wafers which allows for the 3-dimensional integration of various terahertz receiver components in extremely small packages which easily leads to the development of 2-dimensioanl multi-pixel receiver front-ends in the terahertz frequency range. Integrating antennas with terahertz front-end elements has been challenging as most of the planar antennas are too lossy at these frequencies. In this presentation we’ll also explore novel horn and lens antenna architectures which are suitable for integration with silicon micromachined receiver systems. It will be shown that using advanced semiconductor nanofabrication techniques it is possible to design, fabricate, and demonstrate a super-compact, low-mass, and highly integrated multi-pixel terahertz array receiver.

These high frequencies support order of magnitude higher bandwidths enabling high-data rate applications. Furthermore, at these high frequencies, thin (mm-range) polymer fibers such as those made from PE,PP, PS, PTFE, are excellent transmission media and exhibit fairly low loss, below 5dB/m. As such, the combination of CMOS mm-wave transceivers, on-chip or on-board antennas and thin plastic fibers leads to an innovative communication concept that is, in certain applications, perform better than optical communication or copper wireline communication. Especially for cases where high EMI resilience, high mechanical tolerance and low costs are important, such as automotive communication, this 'RF over Plastics' concept can be a game-changing technology. This presentation will discuss some of the key benefits and drawbacks of polymer microwave fiber technology and will present the results of the ongoing research at KU Leuven on this topic since 2012."

In spite of the physical limitations related to device speed and cutoff frequencies, circuit design techniques have been implemented to enable integrated terahertz systems well beyond these frequencies. THz imaging in silicon is example of this approach, and can potentially enable new applications in this range. The large available bandwidth from 0.3-3THz combined with on-chip multi-element integration can enable novel imaging perspectives.  However, enabling this system in a cost-effective and scalable fashion presents significant challenges not only in the realm of circuit design, but also in the co-design of the entire system. Many challenges are still to be addressed, starting with availability of efficient sources with high radiated power, improved tuning range and coherence. On the receiver front, detectors are also in need of improving their sensitivity. These considerations have led to active imaging approaches and systems have been demonstrated with these methodologies. This workshop presentation will focus on recent work that addresses these challenges in silicon technology. This will cover circuit realizations in CMOS technology for terahertz generation and detection, as well as novel imaging approaches."

While a number of novel use cases and services are being contemplated, there is consensus that data demand will continue to grow, putting further pressure on already congested spectrum. Millimeter-wave bands have been cited as having the potential to alleviate some of this pressure. This talk will cover the opportunities and challenges with mobile communications in the millimeter wave band for the deployments and use cases of interest. Specifically, the talk will first cover material and channel propagation measurements highlighting the contrast with sub-6GHz propagation. With those observations, a number of system design principles and associated device/component level requirements will be outlined. Finally, taking some of the design principles and component level considerations into account, coverage and capacity modeling results will be presented.  Some test results from our first generation prototype system at 28GHz will also be presented"

We will introduce new analysis techniques that help us explain and understand how key RF parameters like nonlinear distortion, energy efficiency, and phase-noise will have to be revisited in derivation of future circuit design requirements. The theoretical predictions will be complemented with experimental results obtained using Chalmers 30 GHz massive MIMO test-bed. The second part of the presentation will be devoted to the design of critical mm-wave circuits for 5G base stations. Starting from 5G base station requirements, we will present an integrated 30 GHz SiGe BiCMOS transmitter lineup comprising the co-design of analog pre-distortion linearization, I/Q modulator, and efficient Doherty PA circuits. The excellent results obtained demonstrate the capabilities offered by advanced semiconductor technologies, and indicates a possible direction towards realization of efficient and linear transmitters for next generation wireless systems."

More recently, the need to maximize the performance and reduce the cost lead the PA and digital pre-distortion (DPD) algorithms to a joint development. For the future, besides the referred performance maximization and cost reduction, the 5G systems will add an extra parameter, the integration. Considering that the massive MIMO antenna structures (for frequencies below 6GHz) might contain 64 or more antenna elements (each one with an associated PA), it is evident that to achieve the requested objectives, the PA design cannot be dissociated from the remaining front-end blocks. This factor is even more visible at mm-Wave frequencies, at which the physical dimensions are so stringent that integration is even more important and the technology limitations forces more innovative designs."

Such applications place significantly different requirements on the systems, including link range, mobility and coexistence, resulting in far more stringent circuit requirements, such as higher transmitter output power, stricter transmitter linearity, and agile beam-steering in large-scale phased-arrays. In addition, advanced communication paradigms, such as full-duplex and massive MIMO, are being considered to further enhance the spectral efficiency and data capacity.

As a result, advanced filtering devices capable of meeting the very stringent requirements demanded by these systems need to be conceived. In particular, acoustic-wave (AW) filters have been the key filtering technology of mobile transceivers due to their high quality factor (>10,000) and miniaturized volume (<4 mm3). However, due to their ultra-narrow fractional bandwidth, limited type of realizable transfer function (band pass type), and lack of reconfiguration, the scaling of RF front-ends to multiple bands and wide-band signal processing remains as a great challenge. Within the scope of this workshop, new hybrid-lumped-element-AW-based filter developments that allow to overcoming the aforementioned shortcomings in terms of bandwidth, multi-band operation, and transfer-function adaptiveness will be presented. Moreover, RF interference-mitigation techniques for ultra-wideband wireless communications transceivers based on new broad-band filtering components with fully-adaptable in-band notches will be described. It is believed that these filter design techniques will be essential for upcoming wireless communications systems including 5G."

For mm-wave communications, beam-forming technique and/or Massive MIMO are indispensable technologies, so new requirements for RF front-ends have been emerging for both mobile terminals and base stations. 
This presentation describes the challenges for higher and wider frequency range application of RF front-end devices and modules.  For a 28GHz phased array unit, Antenna integrated Module (AiM) with small size and high performance modules including not only RF-ICs, amplifiers and passive components but also antenna pattern using a low temperature co-fired ceramics (LTCC) is one of the key technologies. Heterogeneous integration and 3D structure lead to the size reduction and low loss. Furthermore, a quartz waveguide Band Pass Filter (BPF) and a miniaturized circulator for 28GHz improve the massive MIMO antenna system. Expansion to 60GHz antenna array integrated modules and sub-6GHz reconfigurable RF front-end architectures are discussed. Accurate and high speed measurement technologies for mm-wave antenna module performances are also introduced."

Depending on the choice of antenna plane, link budget and beam steering concept, the required transmitted output power of the Front End Modules (FEM) is in the range of 15dBm to 30dBm. Besides the challenge to deliver this level of power at mm-wave frequencies in silicon technology, efficiency becomes a crucial design parameter as case cooling of the antenna panel with more than 100 FEM units is preferred. In this presentation we will discuss techniques to realize silicon-based RF PAs for these power levels at these mm-wave frequencies and elaborate on thermal design and packaging. In this workshop we will discuss a 5G mm-wave transmit line up with 18dBm output power and an integrated 30dBm PA for backhaul communication, both realized in an in-house SiGe:C BiCMOS technology."

This was fueled in large part through Moore’s Law, coupled with research and development of new highly-integrated, silicon CMOS devices which transformed large bulky transceiver components into a single chip for wireless applications. These single-chip radios freed up valuable space for more memory and powerful processors, making the modern smartphone, as we know it today, so common and ubiquitous. Although the architectures, circuits, and system-level design methodologies to realize these low-cost, highly-integrated RF ICs have largely been defined, questions remain on how to enable chips for emerging applications in an era of large scale data acquisition, and communication, for a variety of devices  ranging in use from wireless sensing, to high-speed mobile communication and radar. A common theme among these future devices is the need for highly-integrated ultra-broadband (10GHz+) transceiver solutions. However, achieving high bandwidth in the mm-Wave band becomes challenging without burning excessive power and occupying an absolute minimum silicon area, particularly in phased-array applications where numerous elements are replicated on the same die. This presentation explores recent work which attempt to achieve extremely high bandwidth transceivers while utilizing the smallest silicon area possible."

            string(2171) "A major challenge for low-cost silicon-based mm-wave wireless systems, e.g., the 5G MIMO communication links, is to provide large transmitter (Tx) output power (Pout) with high energy efficiency and linearity from a limited supply voltage, so that the high path loss and limited link budget at mm-wave can be compensated. Power combining is often required for these mm-wave Tx. The existing power combining techniques are mainly in two categories. Passive networks can combine the Pout from multiple power amplifiers (PAs) and feed the single antenna port. However, lossy power combiners and large impedance transformation ratios degrade the total Pout delivered to the antenna and lower the Tx efficiency. Alternatively, spatial power combining using antenna array increases the total EIRP but at the expense of a large array panel size. Moreover, a large antenna array often presents an exceedingly narrow (or even pencil-sharp) beam-width; this complicates the Tx/Rx alignment and is challenging for dynamic and mobile mm-wave applications, such as 5G links. In addition, adding silicon lens enhances EIRP but increases cost and packaging complexity. 
   In this talk, we present a concept of multi-feed antenna (MFA) and its co-design with mm-wave transmitters; MFA can be viewed as multiple electrically small antennas that are driven concurrently by multiple feeds but radiate collectively and efficiently as a single antenna. Such an MFA structure naturally allows on-antenna low-loss power combining from multiple PAs, radiation impedance down-scaling, and boosting total output power in one single antenna footprint. We will present multiple MFA designs at different frequencies to demonstrate the concept. We will also present a 60GHz linear radiator element in a 45nm CMOS SOI, as an on-chip MFA driven by 16 linear PAs. The radiator IC generates 27.9dBm Psat and 33.1dBm peak EIRP with 23.4% PAE at 59GHz, showing the best reported mm-Wave PA/transmitter performance in the 60GHz band. Without any signal pre-distortion, the radiator IC achieves -21.9dB EVM with 20.2dBm Pavg for 4Gb/s 16QAM signal, and -25.4dB EVM with 19.3dBm Pavg for 4.8Gb/s 64QAM signal."

Built-in testing and built-in self-testing (BIST) for RFIC is an attractive solution for RFICs but with increasing carrier frequencies the access to the high frequency outputs of the circuits, especially at mmW frequencies becomes very challenging if a minimum impact on the circuit performance has to be preserved. Non-invasive, contact-less techniques using indirect measurements, such as the local temperature increase have been recently proposed to tackle this issue. Other recent BIST techniques are based on replica circuits. We will introduce in this talks these innovative BIST technique for mmW integrated front-ends."

These millimeter wave devices may not have a physical test port, requiring test equipment to connect wirelessly and calibration methods that correct for the air interface.  This presentation introduces challenges associated with Physical Layer (PHY) testing of  SoC at Millimeter Wave frequencies; then it discusses generation and analysis tools offered by Test and Measurement vendors to improve signal quality measurements at these frequencies.

(2) A consideration of millimeter wave frequencies around and above 70 GHz where the spectrum is less crowded and greater bandwidth is available. (3) The idea of base stations equipped with a large number of antennas that can simultaneously accommodate many co-channel users. This idea is referred as MIMO.
However, the next generation multi-antenna transceivers must also provide sufficient output power with great radiation selectivity and directivity. This notion is calling for new generations of MIMO transceivers that also provide beamforming forming and spatial power combining. This talk will be going through latest advances in this exciting domain."

The low-voltage, fast speed, fine feature-size and low cost of the new technology have forever changed the way we design circuits, architectures and systems. Not only the RF/mm-wave circuits have taken different shapes from what has been taught in textbooks but also their integration with digital processors have enabled new possibilities for digital assistance The motivation of this workshop is to capture what is the state at the edge of technology, what is the demand of the industry in the context of high volume products, as well, what are circuit and architectural concepts that are demanded or enforced by the technology. Hence, the idea is to capture and summarize the trends and directions RF design is heading to, which makes it highly valuable from early researchers to long time experienced experts as well as technology scouts."

It is based on mathematical principles and techniques, such as Riemann’s integration or Fourier’s transformation. These mathematical tools are used to optimize a specific signal processing and conditioning. A given tool behavior is then copied as much as possible within a silicon implementation, yielding to mixed-signal integrated circuits that demonstrate innovative system architectures and disruptive approaches. While using Design by Mathematics does not imply one will achieve better performances than when using classical design techniques, it offers a substitute that can counteract key technical bottlenecks and pave the way to new opportunities.

In this talk several Design by Mathematics examples will be presented, focusing on wireless systems. These systems include next generation standards such as 5G and its carrier aggregation technique in the radio frequency range. Fourier’s and Walsh’s transformations will used, as well as Fourier’s recombination and Riemann’s integration, for either the receiver path or the transmitter path of a system."

This architecture simplifies the LO and clock generation, while it also prevents oscillator pulling and spurs which are notorious for classical narrow-band multi-tuner solutions. An implementation of a wide-band HD radio & DAB/T-DMB receiver will be shown, demonstrating best-in-class blocker performance (DAB FoS up to 70dBc) in combination with state-of-the-art DAB sensitivity down to -102dBm. The design aspects of a high-performance 2.2GHz DS ADC with -102dBc THD are presented that also enables the wideband fixed-oscillator receiver concept for the very performance demanding automotive AM/FM radio standards."

RF front-end, transceiver, and modem architectures that could offer the highest (by humans noticeable) data-rate in handsets would be the obvious winner, no matter what RF frequency they ‘pick’ from the air.
In this presentation, the sub-6GHz cellular transceiver architectures would be compared to the sub-60GHz and sub-30GHz mmWave transceiver architectures in terms of performance, area, power consumption, and cost.
Could the big bandwidth of the mmWave design win over the high-order modulation schemes of the well-established cellular design?
Or would the cellular and mmWave transceivers have to co-exist and co-work together for the best of both worlds?
These are just two of the questions that will be addressed in this presentation."

In the WiFi ecosystem, for example, we have seen the addition of the new Gb/s flavors of 802.11ac and 802.11ad (WiGig). Hence, new WiFi-supporting devices have to deliver superior performance in each of these standards, and should operate seamlessly from standard to standard. These requirements demand replacing traditional designs with innovative solutions at system, architecture and circuit levels. In this work, we tackle the physical level challenges with a configurable transmitter architecture. This work demonstrates the concept of a single-PHY transmitter baseband architecture for 11ac and 11ad standards, as a supporting example. The core of the proposed transmitter is a configurable mixed-signal digital-to-analog converter, which has been fabricated in 28 nm FDSOI technology. It embeds semi-digital filtering tailored for four WiFi modes (20, 40, 80 and 160 MHz bandwidths) and the 1.76 GHz bandwidth of the 60 GHz WiGig standard."

Current military architectures will likely include disaggregated systems of smaller platforms working collaboratively to execute missions at lower cost and with increased responsiveness. Commercial enterprises such as OneWeb are looking to cover the globe with broadband access through thousands of LEO satellites. And NASA continues to push state-of-the-art in deep space sensing constrained by very low power satellite systems. With low-power and high integration capability, CMOS technology provides a platform for creating a System-on-Chip (SoC) with digital, mixed-signal and RF/mmWave circuitry for SWaP reduction. This workshop will discuss issues and challenges relevant to the design and reliability of CMOS technology requirements for space based electronics. The workshop will start with a review of a CubeSat electronic requirements, progress through radiation and semiconductor effects and delve into system demonstrations of space electronics for digital and RF/mmWave. This is a great start for engineers to be acquainted with the adventure of space."

Since the CubeSat’s invention and subsequent release of the CubeSat Design Specification it has been widely and successfully adopted by many educational and research institutions. These institutions have used CubeSats to space qualify new technology and provide new science measurements to many under-served research communities. Recently, CubeSat’s have gained more traction in commercial and other governmental sectors focused on operational use. This has driven a need for new capabilities that still adhere to CubeSat standards while keeping with the risk tolerant design nature that allows for innovative mission designs and technology demonstrations."

This trend has been magnified by the number of organizations designing, building, and deploying platforms to low-Earth orbit and other locations in the Solar System.  This increase has been driven by many factors, including ever-improving radiation-hardened by design (RHBD) techniques as well as serendipitous radiation tolerance in advanced technology nodes.  Furthermore, many current and future aerospace applications demand capabilities that can only be realized with device feature sizes at and below 40 nm, 3-dimensional integration, and other techniques considering the substantial constraints placed on size, weight, power, and cost.  In addition to application-specific integrated circuits (ASICs) and more traditional radiation-hardened components, many aerospace organizations are also expanding their use of automotive-grade devices and other enhanced commercial-off-the-shelf (COTS) offerings in order to expand the design space while trying to constrain risk.  While advanced semiconductor device technologies enable many critical applications, their utilization in the space environment requires special considerations."

With no fragile gate oxide, the silicon MESFETs can be designed to have breakdown voltages in excess of 30V, greatly exceeding that of the baseline MOSFETs. MESFETs with gate lengths as short as 150nm have current drives of >1A with fT and fmax greater than 30 and 45GHz respectively. They are also radiation tolerant (TID>300krad) and capable of operating over a wide temperature range (-180° to +150°C) making them ideally suited for space applications in extreme environments. This presentation will focus on the DC and RF characteristics of MESFETs fabricated using a 45nm SOI CMOS technology. Data from total ionizing dose measurements will be presented along with a wide temperature range TOM3 Spice model. The ability to integrate enhanced voltage MESFETs on the same die as ULSI CMOS has the potential for significant savings in size, weight and cost for space electronics, with the added benefit of increased reliability. As demonstrators for the integrated 45nm SOI CMOS-MESFET technology we will describe results from an unconditionally stable low-dropout regulator for point-of-load DC power management, and an RF power amplifier with Pout > 1W."

Presented herein are examples of a variety of modules, ranging from ultra-compact, low loss mm-wave filters qualified for space applications to complete PolyStrata phased array developed for NASA next generation instruments for remote sensing. Also discussed is the incorporation of PolyStrata™ passives components in T/R modules that improve the efficiency and increase power output."

The next logical step in computing are millimeter-scale devices with similar features found in today’s smartphones. With thin-film batteries, CMOS scaling, low-power sensors, and advanced packaging, these mm-scale devices have now become a reality.

The objective of this work is to build a single PLL which is sufficiently flexible such that it can be used in a field programmable radio, or a radio system capable of being reconfigured in the field to any of a diverse set of radio communication standards. An obstacle to producing such a reconfigurable radio is that the noise, frequency, and bandwidth requirements for different standards vary substantially, in turn necessitating multiple PLLs, each optimized for a particular application. To meet the goals of our research effort, it is necessary to produce a PLL which is reconfigurable in multiple dimensions yet maintains sufficiently strong performance (in terms of metrics such as phase noise and locking time) such that the resulting synthesizer is still competitive with the best-performing single-application CMOS PLLs, and can therefore effectively replace a set of application specific PLLs.

With this goal in mind, harmonic-tuned SiGe power amplifiers at 28-GHz will first be presented which achieve 35% peak PAE and up to 13% PAE at 6 dB back off. To further improve back-off efficiency, a dual-vector Doherty beamformer is introduced and demonstrated at 60 GHz in SiGe BiCMOS.

MEMS is ubiquitous. For example, a smartphone can have many MEMS components including microphones/speakers, camera focus/vibration controls, micro-projectors, silicon clocks, position/motion sensors, pressure/humidity/temperature sensors, etc. In comparison, RF MEMS have not been widely used despite their promising performance. In fact, like many new technologies, RF MEMS followed the Gartner hype cycle to reach the peak of inflated expectations around 1995, only to crash to the trough of disillusionment around 2010. However, this also implies that they are now on the slope of enlightenment and may soon reach the plateau of productivity if the major challenges can be overcome in a timely manner. The initial hype of RF MEMS originates from their inherent advantages in terms of lower loss, higher isolation, wider bandwidth, better linearity, and lower power consumption compared to silicon CMOS transistors. However, the hype quickly turned into disillusionment mainly due to the reliability issue. Over the following decade, the reliability issue was mostly overcome by careful choice of design, material and bias conditions, more for capacitive switches than ohmic switches. The main challenge then turned into a yield issue, which was largely overcome by fabrication through standard CMOS foundries instead of dedicated MEMS foundries. Now, the main issue of RF MEMS is insufficient performance advantage to overcome the entry barrier faced by any new technology in competition with the entrenched CMOS technology, such as in existing 3G/4G smartphone sockets. In this case, the savior appears to be the necessity for 5G wireless systems to expand above 6 GHz, which can only enlarge the inherent advantage of RF MEMS, especially capacitive MEMS. However, RF MEMS need to quickly increase their integration level with CMOS circuits.

Compared with capacitive RF-MEMS switches, metal contact type switches have large bandwidth from dc to RF frequency and are favored in many wide-band applications. However, the reliability issues associated with RF-MEMS contact switches have been a barrier for wider adoption of the technology. In particular, existing RF-MEMS switches exhibit poor hot-switching life-time due to dielectric breakdown and field emission. In this talk, we present several design methodologies for drastically improving the hot-switching reliability of contact-type radio frequency micro-electromechanical (RF-MEMS) switches. In the proposed design, sacrificial contacts are used together with low-resistance contacts to significantly reduce the electric field across the latter. The lower field strength drastically reduces the contact degradation associated with field induced material transfer. Theoretical and numerical modeling show that the proposed protection scheme introduces minimal impact on the switch’s RF performance. To realize the protection scheme, we introduce a novel mechanical design that allows the correct protection actuation sequence to be realized using a single actuator and bias electrode. As a demonstration, several 0–40 GHz RF-MEMS switches are fabricated using a robust copper sacrificial layer technique. Compared with unprotected switches, the protected switch design exhibits over 100 times improvement in hot-switching lifetime. In particular, we demonstrate 100–150 million cycle lifetime at 1W hot-switching and 50 million cycles at 2W hot-switching before catastrophic failure, measured in open-air lab environment. Further optimization of the structural design and contact materials is likely to further increase the hot-switching lifetime."

However, their operation is limited by narrow fractional bandwidth (FBW, << the electromechanical coefficient kt2), static response and limited type of realizable transfer function (mostly bandpass). In order to address the aforementioned drawbacks, a new class of acoustic-wave-lumped-element (AWLR)-based RF filters has been developed and will be presented at this workshop.

Sensor nodes will soon be deployed ubiquitously, capable of capturing information of their surrounding environment. The next step is to connect all these different nodes together into an entire interconnected system. This “Internet of Things” (IoT) vision has incredible potential to change our lives commercially, societally, and personally. The backbone of IoT is the wireless sensor node, many of which will operate under very rigorous energy constraints with small batteries or no batteries at all. It has been shown that in sensor nodes, radio communication is one of the biggest bottlenecks to ultra-low power design. This research explores ways to reduce energy consumption in radios for wireless sensor networks, allowing them to run off harvested energy, while maintaining many qualities that will allow them to function in a real world, multi-user environment. Three different prototypes have been designed demonstrating these techniques. The first is a sensitivity-reduced nanowatt wake-up radio which allows a sensor node to actively listen for packets even when the rest of the node is asleep. CDMA codes and interference rejection reduce the potential for energy-costly false wake-ups. This radio consumes 116nW active power, which is less than the sleep power of a standard sensor node, while achieving a data rate of 12.5kbps and an energy/wake-up of 287.7pJ. The second prototype is a full transceiver for a body-worn EKG sensor node. Due to size and energy limitations, this transceiver is designed to have low instantaneous power and is able to receive 802.15.6 Wireless Body Area Network compliant packets. It uses asymmetric communication including a wake-up receiver based on the previous design, a 4µW UWB transmitter and a communication receiver that consumes 292µW. The communication receiver has 10 physical channels to avoid interference and demodulates coherent packets which is uncommon for low power radios, but dictated by the 802.15.6 standard. The third prototype is a long range transceiver capable of >1km communication range in the 433MHz band and able to interface with an existing commercial radio. A digitally assisted baseband demodulator was designed which enables the ability to perform bit-level as well as packet-level duty cycling which increases the radio's energy efficiency. At 2.5mA transmit and 378µW receive power, the transceiver is more than 20X more efficient than its commercial counterpart."

New cars out of today’s production are equipped with a lot of different ADAS units - based on radar, lidar or cameras. Specifically the semiconductor industry there are many challenges that are actively worked on. A system level hot debate is ongoing on the subject of central vs. de-centralized processing between the silicon supplier and integrators. Some OEMs, like Audi or GM, are preferring standardized central processing (zFAS – zentrales Fahrer Assistenz System) while companies like Infineon, NXP, TI or NI, as well as ADI are fostering the de-centralized approach. A topic of similar impact on the IC design is the choice of technology with a strong push to full CMOS solutions, instead of staying with SiGe for the RF.

To be able to handle the higher demand of automotive radar systems and to reduce the system costs at the same time, it is necessary to increase the level of integration, especially on the high frequency (HF) front end side. Traditionally the radar market was dominated by HF bipolar semiconductor based transceivers. For a higher level of integration and to fulfill the high demands of HF performance different technologies like bipolar complementary Metal-oxide-semiconductor (BiCMOS) are necessary. This shift in technology favored a more “digital” centric transceiver partitioning, although the traditional analog HF-architectures (e.g. HF VCO, power amplifier, HF mixers) remained in bipolar technology. It also offers the possibilities of new transmit modulation concepts, and especially in digital front end (DFE) enhanced receiver architectures. Another important aspect for higher integration is the growing demand on monitoring functionality with high coverage to fulfill the requirements for an ISO26262 compliant design.

Specific areas of focus will range across uncertainty in measurement, modeling, and the correlation between the two. The processes that can make measurements appear uncertain, along with the two main methodologies that are currently being used for evaluating the size of a measurement’s uncertainty, will be examined in detail. A new real-time uncertainty approach for modern Microwave systems will be shared. Further, a new nonlinear verification device will be presented, with an exploration of the device performance and an improved Figure-of-Merit. Regarding the modeling and simulation domains, eye-opening insights for Electromagnetic simulation errors will be reviewed, as will the compounding of modeling uncertainties and errors that can form in simulations when complex RF Modules are designed. In deeper computational discussions, the measurement and modeling of stationary and cyclostationary stochastic Electromagnetic Fields will be reviewed, and an introduction to fundamental aspects of the mathematical theory of uncertainty quantification in computational physics will be delivered, from an engineering perspective. The two families of uncertainty quantification techniques, namely non-intrusive and intrusive, will be also discussed.

In large-signal Nonlinear Vector Network Analyzer (NVNA) measurements, however, linear calibration standards are insufficient and the development of a stable and accurate nonlinear verification standard has been a hot research topic for several years now. One of the main scientific challenges is to make the performance of the nonlinear verification device insensitive to the surrounding measurement instrument itself (for example, test port mismatches and DC bias variations). This talk will review state-of-the-art nonlinear verification standards and present the design of a new and promising nonlinear verification device. It will be shown how non-ideal instrument characteristics such as test port mismatches and DC bias variations influence the device performance.

The development of high performance nanoelectronic integrated circuits and systems with increased functionality, high bandwidth and low signal power levels requires EMI-aware design. Such a design has to be based on accurate signal- and noise modeling to minimize the uncertainty in the operation of the circuits and systems. In this contribution we present advances in measurement and modeling of noisy electromagnetic fields using two-probe scanning and correlation analysis. Stochastic electromagnetic fields with Gaussian amplitude probability distribution can be fully described by auto- and cross correlation spectra of the field components. In case of digital circuitry clocked by a single clock pulse, the generated EMI is a cyclostationary process where the expectation values of the EMI are periodically time dependent according to the clock frequency and which have to be considered in modeling the EMI. Correlation analysis provides a basis for accurate modeling of noisy electromagnetic fields and, for strategies in computer aided design to reduce EMI. The determination of the near-field correlation spectra of the EMI radiated from devices and circuits by two-point measurements as well as methods to compute from these data the EMI distribution in complex environments are described. The amount of data required for the characterization of stochastic EM near fields can be reduced considerably by principal component analysis.

The origins for many of differences can be often traced to approximations or assumptions made during the simulation or measurement process (or both!). Such sources of uncertainty may include: approximations in numerical methods, imperfections in solid models, improper definition of electromagnetic port configurations, flawed material parameters, dynamic or inconsistent measurement environments, and potential drift or missteps in calibration. A detailed understanding of the electromagnetic fields, rather than just the port parameters, can aid in our understanding the origins of the differences.

A massive increase in the number of interconnected devices concurrent to IoT would strain the existing infrastructure, making some form of decentralized device-to-device or peer-to-peer (P2P) communication desirable. In order to manage the power consumption of P2P wireless links, duty-cycled radios have often been proposed due to their ability to shut off the static power consumption at low data rates. While earlier radio nodes for such systems have been proposed based on sleep-wake scheduling, such implementations are still power hungry due to large synchronization uncertainty (~1µs), and do not offer a scalable solution for large networks. A unique pulse-coupled oscillator based synchronization mechanism can be used to facilitate the network synchronization leading to both low power as well as scalable network realization. Pulse-coupled oscillator synchrony is modeled on a natural phenomenon observed in Southeast Asian fireflies, which are thought to use each other’s flashes to drive the network to flash in unison. This underlying theory can be used to synchronize radio networks, i.e. control the sleep-wake time of the radios, resulting into ultra-low power design. The talk will delve into the following: 1.) Duty-cycled Radios, and their effectiveness in low power applications. 2.) Timing and synchronization requirements for duty-cycled radios. 3.) Implementation of a scalable synchronization scheme based on naturally occurring phenomenon (fireflies blinking together). 4.)

But in reality, these two constraints are closely connected. Indeed, with the increase in the number of nodes in the mesh, the network becomes more and more congested. The only solution to decongest it, is to enable the radio to communicate at a higher data rate so that the system can be effectively duty-cycled. Now, in such a heavily duty-cycled system with high peak data rates, the average energy spent for communication becomes comparable with the energy overhead of the radio. In traditional radios employing synthesizers based on analog or digital PLLs, the energy overhead is dominated in by the energy required to wake-up the radio. The wake-up time is actually mostly determined by the very high Q of the crystal oscillator (XO), which at the same time also sets the phase noise performance. The wake-up time can be shortened without deteriorating the phase noise by building a loop-free frequency synthesizer based on an RF oscillator using a high-Q resonator such as a FBAR. But due to the frequency stability of the FBAR (after compensating for its frequency variations with temperature), tuning the synthesizer over a wide frequency range is extremely difficult. This talk will show different solutions to this problem and techniques for building low latency loop-free synthesizer."

Certain limits on the allowable values of transistor noise parameters are established and possible limits of low noise performance upon further scaling of gate or emitter size discussed. Widely published concepts in the treatment of noise in transistors and amplifiers, amongst those “gate induced noise” in FETs, wideband low noise amplifier design, CMOS “noise cancelling” amplifiers, are critically examined. The second talk reviews standard techniques to determine the noise performance of 2 port microwave networks, including a recent procedure extending the noise parameters characterization to N port linear networks. The implications to the measurement of differential amplifiers will be addressed. Then, the talk will focus on a novel, tuner-less procedure particularly suited for the determination of on-wafer microwave transistor noise parameters because solely based on transistor size. The third talk discusses the paradoxes of mixer noise characterization, shows how well established noise characterization methods can be applied to mixers, and presents established and advanced methods for optimizing mixer noise figure in both passive and active mixer circuits. Finally, the last talk addresses the question of how to simulate noise in nonlinear circuits. After an introduction on how nonlinear effects such as upconversion of 1/f noise are simulated in time and frequency domains, special emphasis is placed on modeling GaAs and InP HBTs and GaN HEMTs. The talk will also discuss how nonlinear excitations may impact the properties of flicker and white noise sources from the physical standpoint, and how to reflect this behavior in a large-signal transistor model."

The current best noise performance is achieved by InP HFETs with gate as short as 35 nm. The rapid advances in technologies of HBTs (Microwave Heterostucture Bipolar Transistors) and CMOS pose a question whether these transistors can in the future offer alternatives to the extremely low noise performance of InP HFET’s (including their pseudomorphic and methamorphic versions). In order to compare these very different technologies noise models of unipolar and bipolar transistors are reviewed with emphasis on their common noise properties. Certain limits on the allowable values of transistor noise parameters are established proving that in practice any microwave transistor may be characterized only by three noise parameters, instead of four required for linear two ports in general. Experimental confirmations for III-V FETs, HEMTs, HBTs (in several different technologies including GaN HEMTs), and CMOS devices are shown. The question what determines the minimum noise temperature of either FET or BT and the current state of the art are briefly reviewed both at the room at the cryogenic temperatures. The possible limits of low noise performance upon further scaling of gate or emitter size are discussed. Widely held and widely published concepts in the treatment of noise in transistors and amplifiers, amongst those “gate induced noise” in FETs, wideband amplifier design, CMOS “noise cancelling” amplifiers are critically examined.

In either case, the measurement system is fundamentally tailored to measure 2 port devices and its adaptation to the characterization of modern differential amplifiers is not as straightforward as in the single ended case. Indeed, there are some clear limitations to the standard techniques in use when multiport networks are tested for noise figure or when transistors’ noise parameters are sought at high frequencies above the capabilities provided by commercially available tuners.

Once this rusty creaking door is forced open, the analysis poses few problems and shows how the combined output power can be controlled over a useful range and with enhanced efficiency by varying the differential phase of the two input signals. But in almost all other applications and PA analyses transistors are not usually considered to behave as voltage sources, and as such it is surprising that after 80 years the outphasing configuration still sits on such shaky foundations. This paper analyses the Chireix outphasing circuit using a novel analytical model for the transistor I-V knee characteristics, rather than the approximation of a simple voltage source. It also incorporates input drive level variation, usually a critical independent variable in any other PA analysis, but curiously underrated by the RFPA outphasing community.

In the more distant future, these space-based networks may extend to serve manned and unmanned space missions throughout the solar system. We refer to these emerging networks as the Internet of Space (IoS). For example, Google and SpaceX recently announced a $B investment in a plan to deliver hundreds or thousands of micro satellites into LEO around the globe to serve Internet to rural and developing areas of the world. SpaceX’s ultimate goal is building a bridge to a future manned colony on Mars. Similarly, a new venture, OneWeb, is proposing a 648 satellite LEO constellation, with significant investments from Virgin Group and Qualcomm. Facebook and Google already have begun laying plans to serve under-wired markets with drone-based and balloon-based data networks. The European Space Agency and AirBus Defense & Space are planning a “Space Data Highway” that features EO satellites at GEO, and a set of LEO satellites to provide a hybrid optical / RF network for Emergency Response, Open Ocean Surveillance, UAS communication, Weather Forecasting and Wide-Area Monitoring on the impacts of human activities on state of natural resources (deforestation, loss of biodiversity, water/air pollution). Facebook is leading “Internet.org” to bring together technology leaders, nonprofits and local communities to connect the two thirds of the world that doesn’t have internet access. The Space-based networks represent the final frontier in the competition for connectivity. Back in the 1990’s, there were a number of large space-based satellite network ventures, such as Iridium, GlobalStar, Teledesic, etc. but only limited number of low-data rate (kbps) satellites were ultimately deployed. However, since that time, satellite technology has greatly advanced, bringing the cost of deployment down significantly. “Toaster-sized” micro-satellites can be launched dozens at a time to low earth orbits (LEO), reducing launch costs, while delivering performance comparable to larger, older satellites at higher orbits. Also, operation at LEO, satellites will also significantly reduce network latencies, while introducing challenging tracking, synchronization and handoff issues. Advances in microwave/mm-wave phased array technology and advanced CMOS over the last several years will also be key enablers. The new networks should not be expected to replace terrestrial networks, but will integrate seamlessly with these networks to provide ubiquitous global connectivity. Together with several other IEEE Societies the MTT-Society has launched an IEEE Internet of Space Future Directions Initiative in order to promote the future of satellite communication and sensing worldwide."

Furthermore, it should be low cost and adaptable to the higher frequency range, which might be an alternative for future satellite communication, due to the large available bandwidths. These challenges can be met by using electrically tunable systems such as 2D-steerable phased array antennas based on liquid crystals (LCs).

While much progress has been made in clinically relevant investigations, clinical translation has been limited. In vivo, physiologic tissue does not display specific THz frequency spectral signatures and features identified in the excised tissue are often difficult to observe in vivo due to the large aqueous background present in all tissues. Model based analysis has also been limited as THz frequency electromagnetic models are highly sensitive to tissue morphology. In practice, physiologic variation is so broad that it is nearly impossible to apply most models a priori. These issues are all compounded by biophotonic systems (optical imaging designs based on UV/VIS/IR spectra) that often offer similar or superior performance for a fraction of the cost and complexity. In light of these issues our group has chosen to focus on three applications which we believe are ideal for THz diagnostic imaging technology. The first two are acute burn wound severity assessment and surgical flap viability assessment. In both cases, the immediate physiologic response is characterized by massive changes in tissue water content (edema) allowing a THz based system to generate significant contrast without the need for substantial model based analysis or knowledge of tissue morphology. Further, excess tissue water content confounds the measurement of blood perfusion which is the key contrast mechanism of the majority of biophotonic systems thus suggesting a key advantage of THz frequency imaging. The third application is the early detection of corneal diseases that are correlated with changes in corneal tissue water content. Current practice limits diagnostics to the measurement of corneal thickness and extrapolation to water content which itself is incredibly inaccurate and does not account for physiologic variation. While disease related changes in tissue water content are small, the physiologic variation in corneal thickness, as referenced to THz wavelengths is nearly negligible. Thus the cornea can be treated as a thin film and model based analysis can be applied with reliable a priori assumptions on tissue morphology."

However, to peer inside of and help understand clouds, ice processes and the onset of precipitation requires millimeter-wave to THz sensors. At the same time, the satellite industry has recently experienced the maturation of disruptive technology and manufacturing processes to build and launch U-Class satellites. Commonly called CubeSats, these small satellites feature rapid development cycles (about two years) and low-cost launches (less than $0.5 M) as secondary payloads on missions of opportunity. Specifically, 6U-Class satellites provide healthy margins on mass, power, communications and antenna apertures to accommodate millimeter-wave to THz (90-900 GHz) sensors capable of observing clouds and precipitation on a global basis. A closely-spaced constellation of such remote sensors of precipitation can observe the time evolution of ice cloud processes leading to precipitation with revisit times on the order of 5 minutes. Currently, a 6U-Class satellite is being produced to perform technology demonstration for a constellation mission known as the Temporal Experiment for Storms and Tropical Systems (TEMPEST).

Photoconduction is one of the most promising and commonly used means of terahertz generation, due to availability of high power, wavelength tunable, and compact optical sources with pulsed and continuous-wave operation required for broadband and narrowband terahertz generation, respectively. Here, we present an overview of recent advances in photoconductive terahertz emitters that utilize plasmonic nanostructures to significantly enhance optical-to-terahertz power conversion efficiency by enhancing light-matter interaction at nanoscale. Utilizing plasmonic nanostructures in a photoconductive emitter allows concentrating a larger fraction of the incident pump photons within nanoscale distances from the contact electrodes. By reducing the average transport path of photocarriers to the contact electrodes, the ultrafast photocurrent that drives the terahertz antenna is significantly enhanced and the optical-to-terahertz power conversion efficiency is increased considerably. This enhancement mechanism has been widely used in various photoconductive terahertz emitters with a variety of device architectures and in various operational settings, demonstrating significant optical-to-terahertz conversion efficiency enhancements. We demonstrate that use of two-dimensional and three-dimensional plasmonic nanostructures leads to 2 orders-of-magnitude and 3 orders-of-magnitude enhancement in the optical to terahertz conversion efficiency of conventional photoconductive emitters, respectively, offering a record-high optical to terahertz conversion efficiency of ~10%. We show that the significant performance enhancement offered by plasmonic nanostructures can be utilized to achieve record-high terahertz power levels in both continuous-wave and pulsed operation at optical pump wavelengths ranging from 800-1550 nm."

Therefore, the fixed load condition, which is one of the strongest underlying assumptions in the traditional low-pass equivalent transmitter behavioral models, can no longer hold, and a single-input/dual-output formulation, for the nonlinear dynamic PAs, followed by a multi-input/multi-output network, representing the linear and dynamic radiation sub-system, must be adopted.

These unprecedented demands require new-generation power amplifiers (PAs) operating at millimetre-wave bands and delivering high linear power with wide-bandwidth and high efficiency yet with highly reduced size and cost. Therefore, broadband linear PAs with high efficiency at high PAPR, supporting higher order modulation, is one of the most critical components for a 5G mobile and backhaul system. This requires an novel solution in semiconductor (SC)/device technology in combination with innovative circuit topologies and integration techniques. Si devices are very attractive due to high maturity, complex digital and multifunction capability at a low cost. Whereas III/V compound semiconductors (GaAs, GaN & InP) provide higher power, bandwidth and efficiency. Recently there are enormous advancement in Si/SiGe and III/V PAs, including those on SOI for addressing the high performance and cost simultaneously. This very timely workshop will incorporate a wide range of presentations highlighting the recent trends and the state-of the art developments in semiconductor/device technologies as well as circuit and system design and integration techniques for 5G PAs, including those for Ka band handsets as well as Ka, E, and W bands infrastructure. Workshop will present the latest result and compare performance of novel PAs and PA intensive sub-systems, like RF beamformer, for various circuit and device technologies, and in terms of BW, ACLR, efficiency with high PAPR, and cost. This will include PAs using CMOS/BiCMOS (on Si and SOI), SiGe, GaN (on SOI and SiC) and GaAs.

This workshop presents some of the recent developments on optical and radio frequency technologies for non-contact and wearable monitoring of health information such as respiration and heartbeat. The technologies presented operate in a broad frequency range from a few hundreds of MHz to optical spectrum, with operation range from a few meters to direct-contact detection. Special emphasis of this workshop is dedicated to solutions at both the circuit and system levels. High sensitivity, low cost, and ease of integration with existing consumer electronics such as smart phones are some of the distinguished features of the presented technologies.

Measuring and monitoring any patient's vital signs is essential for their care- in fact, all care first begins by collecting vital signs like heart rate and blood pressure. The current standard of care is based on monitoring devices that require contact - electrocardiograms, pulse-oximeter, blood pressure cuffs, and chest straps. However, contact-based methods have serious limitations for monitoring vital signs of neonates as they have extremely sensitive skin and most contact-based vital sign monitoring techniques result in skin abrasions, peeling and damage every time the leads or patches are removed. This results in potentially dangerous sites for infection increasing the mortality risk to the neonates. OUR SOLUTION? We propose to use normal camera to measure the vital signs of a patient by simply recording video of their face in a non-contact manner. From the recorded video of the face, our algorithm, distancePPG, extracts pulse rate (PR), pulse rate variability (PRV) and breathing rate (BR). The algorithm is based on estimating tiny changes in skin color due to changes in blood volume underneath the skin surface (these changes are invisible to the naked eye, but can be captured by a camera). Our algorithm, distancePPG (patent pending), achieves clinical grade accuracy for all skin tones, under low light conditions and can account for natural motion of subjects. It does so by intelligently combining skin color change signal from different regions of the visible skin in a manner that improves the overall signal strength. Our algorithm results in as much as 6dB of SNR improvement in harsh scenarios, rapidly expanding the scope, viability, reach and utility of CameraVitals as a replacement for traditional contact-based vital sign monitor."

Over 5.2 million Americans have been diagnosed with AF, and the prevalence of AF is increasing concomitant with the aging of the U.S. population. AF exerts a significant negative impact on the longevity and quality of life of a growing number of Americans, predominantly through its association with an increased risk for heart failure and stroke. Effective AF treatments reduce a risk of complications from AF. A major challenge facing clinicians and researchers is the early detection of AF, because particularly in its early stages, AF can be intermittent and asymptomatic. While the population with undiagnosed AF is substantial, studies have shown that more intensive cardiac monitoring can improve AF detection and enable timelier institution of treatment. Automated AF detection algorithms offer real-time realizable AF detection but often suffer from the fact that common benign causes of rhythm irregularity, most notably premature atrial (PAC) and ventricular (PVC) contractions, can cause false positive AF detection. There is a pressing need to develop a continuous arrhythmia monitoring device that can accurately and reproducibly distinguish between AF, NSR, and premature beats (PACs and PVCs) in order to improve patients’ cardiovascular health and reduce the costs associated with treating AF. To this end, we have recently developed a smartphone application for arrhythmia discrimination, which can identify NSR, AF, PACs and PVCs using pulsatile time series collected from a smartphone’s camera. This application detects and removes motion and noise artifacts (MNAs). This talk discusses the development and clinical testing of arrhythmia discrimination. Given the ever-growing popularity of wearable devices and smartphones, our approach to arrhythmia discrimination will give the population as well as health care providers the opportunity to monitor arrhythmia under a wide variety of conditions outside of the physician’s office."

The concept of inversion coefficient IC is first introduced as an essential design parameter that spans the entire range of operating points from weak via moderate to strong inversion. It is then shown how several important figures-of-merit (FoM) including the current efficiency G_m/I_D , the transit frequency F_t, their product (G_m·F_t)/I_D and the minimum noise factor F_min can be expressed in terms of IC to capture the various trade-offs encountered in RF circuit design. It is then explained how short-channel effects, and mainly velocity saturation, have significantly slowed down the increase of F_t and degraded F_min in recent technology nodes. The simplicity of this IC-based model is emphasized by comparing it against measurements from a 40- and a 28-nm bulk CMOS processes and BSIM6 simulations.

The performance, requirements and market opportunities for tunable filters used in wireless systems will be discussed for both mobile applications (FBAR) and base station applications (high-Q filters). Speakers will address technologies such as ferroelectric BST, MEMS, Phase Change Materials (PCM) and active N-Path in the realization of tunable filters.

These filters comprise a large portion of the front-end circuit of the handset and they are typically incorporated into a discrete RF front-end module along with power amplifiers, switches, and control logic. At the present time, SAW, BAW, and FBAR filters are the only known technologies with sufficiently low insertion loss and steep filter skirts which are available in sufficiently small hermetic packages for use as filter elements in front-end modules. The demand to incorporate additional filter functions increases with each successive handset generation. It has been suggested that tunable filters could be used to replace groups of fixed filters to either reduce the size of the front-end modules or to enable more filtering function in a module with a given size. This would also help to reduce the total cost of the front-end circuit. There are, however, numerous monumental technical challenges that make continuously and discretely tunable SAW, BAW, and FBAR filters impractical for use in front-end modules of wireless handsets. A common front-end configuration comprises a bank of filters which are switched in and out one at a time. A reconfigurable filter could be used in place of this switched bank of filters. However, for this to be feasible, the reconfigurable filter would need both frequency and bandwidth tuning “knobs”. To achieve this tunability, schemes have been proposed in which the frequency and kt2 of the constituent resonators of the filter are tuned in discrete steps. For example, banks of switched capacitors in series and in parallel with each resonator could be used for tuning; unfortunately, such banks of capacitors would significantly reduce the Q of the resonators, would occupy significant area and would reduce the power handling capability of a filter. Other schemes have been proposed in which the frequency of the constituent resonators is controlled by a dc voltage or magnetic field. Such devices have poor Q, don't have kt2 tunability, and are inherently non-linear, all of which are seriously performance limiting in the RF front-end. Another idea which has been proposed is to use an ultra-narrow tunable filter with steep filter skirts and a wide tuning range which could be tuned to a particular channel of interest. The problem with such a scheme is that modern 4G and LTE modulation protocols, require that the communication bandwidth vary from 0.2 MHz to more than 20 MHz and constructing a low insertion loss 20 MHz wide tunable filter with sharp filter skirts at GHz frequencies is unfeasible. The tunability problem is further exacerbated in the most recent handset generations where Carrier Aggregation (CA) functionality requires a handset to be capable of receiving multiple signals simultaneously. To enable CA functionality, a set of custom multiplexers is required. Each multiplexer: (1) is comprised of several filters which are attached to a single ANT port through a custom matching network and (2) must meet numerous RF specifications of the handset including not only the individual filter insertion loss, return loss, and isolation specs, but also a set of cross isolation specs between filters. Attempts to design a tunable version of a multiplexer comprising several tunable filters would be impractical because each tuned state of the multiplexer would need to comply with a different set of stringent spec requirements. Specifically, the fixed matching network will prevent the Tx and Rx ports of the multiplexer from having a tight "spot size" (return loss) over the full range of tuning, while the fixed cross couplings in the filter will prevent the precise frequency-placement of the poles and zeroes of filter function over the full range of tuning. Therefore, for the present and medium term, traditional filtering is the architecture of choice. As new bands and as new functionality such as 4-way MIMO are incorporated into RF front-ends, the number of filters per module will continue to increase. To respond to this pressure, technological innovation in piezoelectric filters must enable further reduction in filter size. A review of the evolution of this size scaling will be discussed as well as a discussion of module architectures which allow re-use of certain filters."

High linearity and blocker tolerance is crucial for interference robustness.

They can both offer tunable filter functionality, but also frequency conversion with built-in RF-filtering. N-path filters essentially realize a low-pass R-C or high-pass C-R function in baseband, which is frequency translated to a band-pass or noth filter. As passive switch-R-C networks are used, linearity can be good. Moreover, the frequency translation is controlled by a digital clock, allowing for flexibly programmable very wide tuning range covering more than an octave or even decade in frequency. The resulting N-path filter benefits from CMOS scaling as switch parasitics improve, and increasingly higher digital clock frequencies are feasible.

Higher bandwidths, more complex modulation formats and higher output power put challenging requirements on the hardware for achieving higher data rates. Transmitter and receiver architectures may look quite different from today’s line-up because of the tougher requirements on linearity, noise, efficiency and dynamic range. For the power amplifier in such equipment, the most critical parameters are output power and linearity to be able to use high modulation formats and higher output power for longer distance communications. Digital pre-distortion is nowadays common practice to linearize amplifiers at lower frequencies. Usually for microwave radios, this technique is implemented in the digital domain at the expense of increased bandwidth in the digital/analog converter (DAC). At mm-wave frequencies, when the signal channel bandwidth is much wider, the increased signal bandwidth used in the DAC will consume too high power, making this technique inappropriate to use for enhancing the radio performance. Analog pre-distortion of power amplifiers on the other hand can be implemented at mm-wave frequencies with little or no added power consumption to enhance the linearity. III-V technologies offer the best RF performance. GaAs High Electron Mobility Transistor (HEMT) is the most used and established technology for mm-wave MMICs due to its satisfactory high frequency performance. The reliability, stable manufacturing, performance and pricing of GaAs are very competitive, which make this technology very attractive for commercial use. High bandgap materials such as GaN are emerging technologies that offer significantly higher output power and linearity and is a candidate for being the next generation’s technology.

The superior amplitude-to-amplitude (AM-AM) and amplitude-to-phase (AM-PM) linearity makes the SCPA attractive for implementations in mobile communication systems for latest communication standards such as Universal Mobile Telecommunications System (UMTS) or Long Term Evolution (LTE). In this talk the principle idea of the C-DAC as a configurable capacitive voltage divider, which additionally performs the mixing operation in dependency of the applied LO carrier signal, will be introduced. Two different transmitter structures, the IQ C-DAC based architecture and the polar C-DAC based architecture will be discussed. The C-DAC consists of an array of switched-capacitor cells, where each cell ideally consists of a CMOS inverter and a capacitor. An ideal C-DAC is perfectly linear. However, non-ideal components, i.e. switch parasitics and variations of the capacitors in the cells, cause the C-DAC to become non-linear, and thus generate AM-AM and AM-PM distortions. In addition, imperfect power supply sources generate unwanted harmonics in the C-DAC’s RF output signal. We present a switched non-linear state space model (SSM) which allows studying these effects with significantly reduced simulation run-time compared to circuit simulators. A comparison between the non-linear SSM, a transistor-level circuit model, and measurements on a 28 nm CMOS test chip is given for single tone as well as modulated LTE test signals. Furthermore, we will discuss digital pre-distortion concepts to improve the spectral regrowth behavior and the error vector magnitude (EVM) of an IQ C-DAC based architecture. The approaches have been validated using the non-linear SSM as well as circuit level simulations, and by measurements with the 28 nm CMOS test chip."

The III-V semiconductor-based RF PAs, however, can still offer superior frequency and breakdown performance with higher output power (POUT) and power-added-efficiency (PAE) and faster time-to-market, but silicon-based RF PAs do have the advantages in offering higher monolithic integration with added functionalities (e.g., flexible on-chip digital control and selection on power level, modulation schemes, frequency bands, adaptive matching, predistortion, etc.), which can translate into lower cost and smaller sizes attractive for broadband multi-mode multi-band handset transmitters. The advancement from 4G into 5G will for sure increase the complexity for PA design, as the higher RF signal modulation bandwidth (e.g., 250/500MHz and above 1 GHz) for transmitters, stringent linearity and efficiency requirements at cm-Wave and mm-Wave carrier frequencies (e.g., 15/28/38/45/60/73 GHz), multiple antennas for beamforming and massive MIMO, etc. will be particularly challenging for both 5G PA design and testing. The peak the multiple carriers and clusters may result in more challenging waveforms with high peak-to-average-power-ratio (PAPR) for transmitters. The greater numbers of the supported bands, MIMO antennas and 5G small cells will require many more RF PAs and make the high PAE performance and low-cost particularly attractive; and the significantly reduced 5G PA peak POUT requirements appear to be favorable for silicon-based PAs implementation. Therefore, some potentially key design techniques for high-efficiency 5G broadband wireless PA design will be discussed in this talk. The design and testing challenges ahead for highly efficient linear wideband RF/mm-Wave PA are particularly serious for 5G applications, especially for mm-Wave and massive MIMO-like scenarios.

Only those primary coils located below the secondary coil of a vehicle are excited. By this way losses and radiation in the environment are minimized. The operation principle of the moving field inductive power transfer system is based on a switched DC-to-DC converter which converts the DC power supplied by the stationary power line to DC power delivered to the moving electric vehicle. The dynamics, the operating regimes and the power balance of the moving field inductive power transfer system and the costs for the implementation of the system are discussed. The contactless power supply of electric vehicles on highways makes it possible to get along with battery capacities otherwise suitable only for shorter range. The batteries are used only in local traffic and on side roads where no moving field inductive power transfer system is installed. In areas where there are no inductive supply roads available, the inductive energy transmission system may still be used in stationary charging stations. Since only the primary coils below the vehicles are activated, high efficiency is achieved and the magnetic field is shielded against the environment.

This research has proven that significant wireless power can be transferred over relatively large air-gaps efficiently and robustly. Early solutions were applied in industrial applications to power moving vehicles in clean room systems, roadway lighting, industrial plants, and in theme parks, but more recently this research has helped develop technology that has the ability to impact us directly at home. The seminar will describe some of the early motivations behind this research, and introduce some of the solutions which have been developed by the team of researchers at Auckland over two decades, many of which have found their way into the market.

This presentation addresses the design challenges and the tradeoffs associated with the design of a multi-modular capacitive WPT system suitable for stationary and in-motion EV charging. The system utilizes relative phasing of the different modules to achieve near-field field-focusing and hence maintains fringe fields within safety limits. The WPT system also requires matching networks that provide large voltage or current gain and reactive compensation. An analytical optimization approach for the design of L-section multistage matching networks is developed and utilized to maximize the matching network efficiency.

To make such systems a reality, our group works on a number of critical aspects: 1) microfluidics-based dielectric spectroscopy with precise temperature control, 2) multi-physics modeling and design of microfluidic microwave heaters, and 3) characterization of the performance of microwave heater designs using synchronized fluorescence measurements (Rhodamine). To enable this, we have developed an experimental platform that combines dielectric spectroscopy (300 kHz – 26.5 GHz) with high-speed multi-channel fluorescence microscopy and temperature measurements using integrated Pt resistors. In this talk, we will give an overview of our experimental setup and its capabilities. We will also discuss our heater designs which were realized in a variety of technologies (LCP, HR-Si, waveguide) for applications on different scales (nl to ml volumes).

Healthcare processes are no different and the trend is to give patients a custom made treatment. For this purpose, theranostic devices or systems are well suited since they provide a combination of diagnosis and therapy in a single device or system. Although the theranostic field is very broad, for certain applications microwave devices can play an important role by combining high sensitivity, good penetration and spatial resolution as well as marker- and reactionless operation. As a result, state of the art devices that can perform diagnosis, treatment or both with great advantages over classical methods are explored with great interest and will be possibly available in the next years. Some of these advantages are minimal invasive procedures, reduction of risk for the patient and secondary surgeries, faster recovery time and lower costs. In this talk will be first presented an overview of the theranostic field, what does the word mean and how electromagnetic devices can be integrated. Then the talk will focus on minimal invasive microwave devices for cancer therapy. These devices are theranostic instruments since they can make a diagnosis by analyzing the relative dielectric change between healthy and malignant tissue and perform treatment with thermal ablation. This is possible since the sensor and the applicator are based on identical electromagnetic interaction principles and can therefore be combined in a single theranostic instrument. The sensor element is based on microstrip/coplanar excited split ring resonators (SRR). The initial prototypes were bulky and could only detect the dielectric properties of organic tissue. Extensive work was done to reduce the size and its packaging to include them in a needle-like minimal invasive tool and create a second operation mode where the tissue could also be ablated with the same device."

However, contemporary standard diagnosis methods such as e.g. sonography and angiography, show significant shortcomings in providing necessary data as a basis for efficient treatment of the various manifestations of atherosclerotic plaques. It is furthermore especially desirable to combine diagnostics and therapy in a single step operation, making miniaturized, compact, easy-to-combine diagnosis tools indispensable. The presented new method allows differentiation between lipid and calcified plaques based on dielectric characterization for early diagnosis and better therapeutic options. The nearfield sensor presented in [2] was developed in 130 nm SiGe technology and allows minimally invasive procedures to detect and categorize plaques in arteries based on their dielectric constant. The sensing oscillator is a common collector differential circuit based on a Colpitts topology which is coupled to a microstrip sensing element. For easy handling in laboratories, the chip is equipped with an RF to DC conversion circuitry to provide DC read-out capabilities. The final flexible polyamide interposer accommodating the chip has a length of 38 cm, a width of 1.2 mm and a thickness of 200 µm. Because of its minimal size the interposer completed a catheter with a diameter of 8F ready for further clinical use in cardiology and heart surgery. The sensor function was successfully tested with calibration fluids as well as human tissue exhibiting both types of plaques.

Neural implants have become ubiquitous with some of them receiving FDA approvals for commercial use recently. Implants powered using batteries have limited life time and a surgical intervention is required to replace them. As batteries have finite recharge cycles, wirelessly charging the batteries only provides an incremental lifetime. Battery-free operation using sustainable wireless powering can extend the lifetime of implants as long as needed. An antenna is one of the most important components to ensure robust link performance. It is a great challenge to design an antenna inside a human body as critical constraints such as biocompatibility issues, antenna size and safety concern should be considered. Besides, due to the complexity and variation of human tissues, wide bandwidth is required in case of frequency shift. In this presentation, different approaches for wireless power and miniaturized antenna used in neural implants will be introduced and their performances are compared against the implant requirements. Then we discuss in detail our wireless platform for peripheral nerve implants with neural recording and muscle stimulation functions starting from the design considerations, power and data link design and safety.

In this talk, we describe electromagnetic structures, termed phased surfaces that interface with non-planar body surfaces and optimally modulate the phase response at microwave frequencies. Unlike phased arrays, the phased surface does not require phase delay or control circuits, enabling its integration into a conformal device. These surfaces can be operated in both the transmitting mode, in which an optimally focused field is generated by rapid phase variations, and the receiving mode, in which evanescent waves are coherently combined.

In most cases, the position of the sensors nodes is critical to the performance of the WSN, thus localization techniques are of considerable interest. Global positioning techniques, such as GPS and GLONASS, do not provide accurate enough positioning, in particular in environments where satellite signals cannot be detected or when the nodes are moving relative to one another. Therefore, local positioning techniques, where the nodes coordinate amongst themselves, are of particular interest. This workshop will give a comprehensive introduction to this topic covering all aspects from theoretical basics in localization, platform design of position aware sensor nodes, and practical examples for signal composition as well as positioning algorithms. The workshop content is illustrated by demonstrative real-world examples for industrial indoor positioning, localization in the Smart Home context and animal tracking. The required positioning accuracy and precision may vary for such systems, but the connecting link is in most cases the limit in resources concerning energy, weight, or size. Therefore, sophisticated resource aware techniques are required for all components of such systems starting from the system configuration, hardware topologies for the sensor nodes, algorithm partitioning between sensor node and base station up to the design of dedicated positioning signaling."

Millimeter-wave bands offer 50 times the bandwidth available in existing RF bands but pose numerous technical challenges to the low-cost deployment of millimeter-wave solutions. For example, U.S. regulators recently issued a notice of inquiry for provision of mobile services above 24 GHz. Additionally, reliable coverage over the typical 200 meter cell radius in non-line-of-sight dense urban conditions, and practical antenna array solutions for user equipment (UE) were both demonstrated at 28 GHz. High-volume implementation of the UE radio is also envisioned as multiple-element phased-array transceiver in silicon technologies. However, a great deal of discussion still surrounds how 5G standards and as a result their corresponding wireless accessories for UE will evolve. This workshop is focused on gathering a combination of experts in mm-wave integrated circuits to discuss integrated circuit solutions to potential mm-wave front-ends for different 5G standards. This workshop will present state-of-the-art research results in this area and ultimately help participants identify the enabling integrated radio technologies for 5G cellular communications."

The technique used for the challenge to integrate multiple T/R modules such as SIP, or multiple layer PCB boards will also be included. For the issue about channel measurement, channel properties are important for wireless communication system design. In 5G communication system, due to the adopt of narrow beam steering function, the channel properties are much different than the conventional channel properties which use omni direction antennas. Therefore, the properties such as the path loss, delay spread, blockage, and coverage have to be measured under the controlling of the angle of arrival (AoA) and angle of departure (AoD). Because the bandwidth is wide in 5G communication system, the resolution of the delay spread have to be high. Both beam steering and the high resolution requirements give the challenge for the design of the channel measurement system. Because the scanning of AoA and AoD, large amount of measurements have to be measured and this is time-consumed. Because the resolution of the delay spread is high, the captured data quantities are large and the processing time is also time-consumed. This talk focuses on the building of the channel sounder which is operated in 38 GHz and for the measurement of the channel properties of 5G system. In this talk, the discussion topic covers the hardware and the software issues. The measurement methodology to achieve fast and accurate channel properties will be described.

The ongoing push to scale electronic devices to nanometer-scale has led to the discovery of new nano-materials and new physical phenomena. Meanwhile, new medical insights and treatments are now enabled by rapid advances in technology that harness our increased understanding of biological systems. Microwaves have a unique role to play in this cross-disciplinary field, for example by providing methods for non-invasive diagnostics and therapies. Furthermore, the development of body-area networks and communications will require a detailed understanding of the interaction of microwave and millimeter-wave radiation with biological systems. Finally, microwave measurements provide a platform non-destructive, spatially-resolved characterization of biological materials at microscopic and nanoscopic length scales. This workshop explores this emerging area, with emphasis not only on new applications, but also on establishing foundational understanding of the interaction of microwaves with biological systems at micrometer and nanometer length scales. One focus of the workshop will be the integration of microwave techniques with microfluidics for a number of applications, including quantitative determination of complex permittivity, local heating, and other microwave-based manipulation techniques. Also of particular interest are microwave probe techniques, including near-field scanning microwave microscopy. Application of such probes to cellular and sub-cellular systems provides non-destructive, subsurface measurement capabilities with nanometer-scale spatial resolution.

In addition to conventional methods of studying electroporation, such as dye techniques, fluorescent cytometry, and patch-clamp techniques, dielectric spectroscopy based methods have become important as a new electronic label-free and non-invasive modality to investigate the phenomenon. This is not surprising as the creation of conductive pores and influx/efflux of molecules cause significant changes in the dielectric properties of the cell. Of interest in many applications is knowledge of how the physiology of the field-exposed cell changes on very short to very long time scales. In this presentation we focus on the time-dependent response of cells exposed to pulsed electric fields of different field intensities and pulse protocols and how this can be measured. In particular, we describe an in-flow dielectrophoresis cytometry technique, which is used to capture and continuously monitor the dielectric change of single cells. The approach uses a microfluidic device with arrays of electrodes for microwave detection, dielectrophoresis actuation and pulsed field exposure of cells. It is sensitive enough to differentiate intracellular electrical properties and relate these to membrane, cytoplasm, nuclear material and structural changes.

This quickly increasing complexity stresses the implementation of the radios since PCB area and power envelope are highly constrained in mobile phones and thus components need to shrink and the power dissipation per function must decrease. Therefore, new concepts are needed in front-end design as well as transceiver architectures.

In addition to traditional filter requirements such as low insertion and return losses, high out-of-band rejection, and good linearity, the design of multiplexers poses a number of new challenges and constraints when designing the constituent filter components. Filters in a multiplexer need to collectively present a relatively high impedance to each filter in its passband, in order to minimize loading and maintain good in-band performance. This necessitates filter co-design methodologies that properly account for loading effects within multiplexers. Proper care is warranted in designing acoustic resonators to avoid unwanted spurious modes from falling in other operational bands within the multiplexer, since these unwanted modes provide a form of resistive loading that adversely degrades in-band performance.

The work presents a methodology that provides a systematic synthesis procedure for designing ladder filters and multiplexers based on acoustic wave resonators. The methodology uses a nodal approach based on resonating (RN) and non-resonating nodes (NRN). This procedure is time efficient, precise in the outcomes, and provides a deep understanding of the particular interactions between technology constraints and device performance. The main advantages of inline extracted pole filters with NRNs are features that can be observed in the well-established acoustic wave based ladder structures: they exhibit the property of modularity, since the position of transmission zeros can be controlled independently by tuning resonant frequencies of the resonators, and they are able to create a fully canonical filter without the need of a direct coupling between source and load, but exists through a reactive path.

This includes removing material where there are current nulls in the resonator structure. A second advantage is the potential size reduction. Because 3D printing can produce complex shapes as easily as simple ones, new types of resonator and/or smaller resonators such as coaxial structures can be easily used.

In parallel, they have also demonstrated optically-controlled variable attenuators and switches within the WR-2.2 waveguide band, from 0.325 to 0.5 THz, using expensive bulk micromachining of silicon. This paper brings both concepts together in the form of realizing low-cost hybrid components and circuits; whereby miniature high-resistivity silicon implants are assembled into 3-D printed split-block MPRWGs having integrated infrared laser diode packaging mounts.

Then individual components are brought together to create the first 3-D printed optically-controlled THz IQ vector modulator.

Next-generation networks must ensure data rates up to 10 Gbps and modulation bandwidths up to 500 MHz, but also eliminate obstacles in today's communication systems, e.g., network reliability, accessibility, energy efficiency and latency. A denser spatial distribution of base stations, communication with MIMO, frequency and service agility of the hardware components as well as integration of the RFPAs into the antenna are pursued trends. The higher modulation bandwidth is enabled by operating the systems at higher carrier frequencies (6 GHz to mm-wave). Meanwhile, path loss increases and the distance between transmitter and receiver is decreased which enables smaller cells but requires more base-stations compared to the current 4G standard. The power per base-station as well as per RFPA hence reduces due to the distribution of the power to several PAs in the MIMO system. Linearizing such MIMO systems also poses a totally new challenge due to the possible RFPA crosstalk. The RFPA as the main energy consumer needs to satisfy the following essential requirements: high energy efficiency for high modulation bandwidths and large PAPRs. In addition, the role of DPD as a “wonder” linearizing method for the future systems can be questioned. The distribute nature of the system severely reduces the expected achievable efficiency improvement by standard DPD applied to each low power RFPA unit. Alternative solutions must be considered. In this workshop, industry and academic experts will discuss demands and various perspectives with regard to efficient, broadband and highly linear systems and circuit design techniques suitable for future wireless telecommunications such as 5G.

This talk will focus on the PA and 5G system challenges that are becoming apparent via the 3GPP standards efforts. There are two general frequency categories for these radios: sub 6GHz and millimeter wave (mmW). When we examine the sub6GHz configurations with higher throughput (TPUT), the goal is to provide better throughput beyond what 4G LTE can provide, both in the uplink and downlink. This additional TPUT will be achieved through wider modulation bandwidth, higher modulation complexity, and multiple data streams (layers). The result of this is a higher peak-to-average ratio and lower EVM specification for the PA (~1%). When we examine the mmW radios, we are faced with another set of issues: wider modulation bandwidth, 500MHz – 1GHz; compromised link budgets due to Tx power levels and propagation channel issues; multiple chains with multiple antennas in a phased array configuration.

However, the classical metallic waveguide technology, which offers better performances such as lower insertion loss and higher power handling, has still been used in the design of microwave and millimeter-wave systems, despite its higher cost and bulky structure. To offer a highly integrated, further loss-reduced, low-cost alternative to the conventional waveguide and also to allow a wide-spread use of the millimeter-wave spectrum, a new SIW structure called Air-Filled SIW (AFSIW) has been introduced. This new structure has been theoretically and experimentally studied in details with a substantial amount of results. At millimeter wave frequencies, compared to the SIW topologies, the proposed AFSIW scheme exhibits a substantially lower insertion loss (three times at Ka-band, for example) and a much higher average power handling capability (four times, at Ka-band for example). Numerous AFSIW passive components have been investigated designed and demonstrated, which take advantages of the well-established multilayer printed circuit board (PCB) fabrication process.

At these high frequencies, plenty of bandwidth is available enabling high-data rate applications. Furthermore, at these high frequencies, thin (mm-range) polymer (PE,PP, PS, PTFE,...) fibers are excellent transmission media and exhibit fairly low loss, below 5 dB/m. As such, the combination of CMOS mm-wave transceivers, on-chip or on-board antennas and thin plastic fibers leads to an innovative communication concept that is, in certain applications, far better than optical communication or copper wireline communication. Especially for cases where high EMI resilience, high mechanical tolerance and low cost are important, such as automotive communication, this 'RF over Plastics' concept is a game-changing technology.
