RFIC 2023 Plenary Talk #2
"Future System-on-Chip for Full Spectrum Utilization from RF to Optics"
The ever-increasing bandwidth requirement due to explosively growing 5/6G and AIoT data flows has compelled global commission authorities to release EM-spectra up to millimeterwave (30-300GHz) and even (sub)-millimeter-wave frequency regimes (>300GHz) for massively expanded sensing and network applications. In this talk, we will exemplify novel CMOS embedded technologies and methodologies developed at UCLA to enable System-on-Chip (SoC) realizations for multi-broadband radio, wideband radar, contactless/plastic interconnect, 3Dimaging and gas-phase rotational spectrometry at (sub)-mm-Wave frequencies, including:
- DiCAD (Digitally Controlled Artificial Dielectric), the only proven Digital-to-Permittivity Converter (DPC), embedded in CMOS-switched interconnects that can vary transmission-line permittivity in real-time (up to X20 in practice) for (sub)-mm-wave frequency synthesis, direct-frequency modulation and reconfigurable (software defined) radio/radar/spectrometer implementations
- Self-Healing Radio (57-64GHz) with self-diagnosis and self-healing capabilities to secure high performance-yield and counter temperature/process variations & aging effects
- Multiband RF-Interconnect, beyond traditional baseband-only interconnect, to enable contactless and/or plastic waveguide communications up to Terahertz with unprecedented bandwidth, efficiency, dynamic re-configurability & multi-cast capabilities
- Fully integrated frequency synthesizer (PLL) at 560GHz and realized 1st active and passive CMOS imagers at 110GHz; 3-color (349/201/153GHz) and 3D imaging radars for sensing/ranging concealed objects
- Single-chip CMOS heterodyne H2O-Detecting Spectrometer at 183 GHz to enable NASA’s space exploration missions with reduced mass (6.5X) & power (5.5X) to meet strict payload and energy consumption requirements
We will also address challenges encountered in both design and implementations that may hinder further development of such systems, especially the major shortcomings in silicon technologies with limited dynamic range and power handling capabilities. We therefore propose replacing CMOS n-FET’s drain with selectively grown wide bandgap cubic-phase GaN (c-GaN) for >10X improved breakdown voltages to secure desired sensing/communication range/coverage with cost-effectiveness.
We also elaborate on the possible growth of multi-wavelength light-emitting sources and detectors directly atop n-FET’s c-GaN Drain with various indium contents of InGaN/GaN superlattice for RF-optical combined radio/radar/interconnect applications by creating unprecedented “Photonic System-on-Chip” with full EM-spectrum utilization from RF to optics.
Dr. M.-C. Frank Chang is the Wintek Chair in Electrical Engineering and Distinguished Professor at the University of California, Los Angeles. Prior to joining UCLA, he was the Assistant Director of the High Speed Electronics Laboratory of Rockwell Science Center (1983-1997), Thousand Oaks, California. In this tenure, he led the team to develop and transfer the MOCVD based AlGaAs/GaAs & InGaP/GaAs Heterojunction Bipolar Transistor (HBT) and BiFET (Planar HBT/MESFET) integrated circuit technologies from the research laboratory to production line (later became Skyworks Solutions). The HBT/BiFET productions have grown into multi-billion dollar businesses and dominated the cellphone power amplifier and front-end module markets for the past 30 years (currently exceeding 10 billion units/year and exceeding 50 billion units in the past decade). Throughout his career, his research has focused on the research & development of high-speed semiconductor devices and integrated circuits for radio, radar, imager, spectrometer and interconnect System-on-Chip applications. He invented the multiband, reconfigurable RF-Interconnects for Chip-Multi-Processor (CMP) inter-core communications and inter-chip CPU-to-Memory communications. He and his students were the 1st to demonstrate CMOS active and passive imagers at mm-Wave (100-180GHz) frequencies. His Lab also pioneered the development of self-healing 57-64GHz radio-on-a-chip (DARPA’s HEALICS program) with embedded sensors, actuators and self-diagnosis/curing capabilities; and invented the Digitally Controlled Artificial Dielectric (DiCAD) embedded in CMOS technologies to vary transmission-line permittivity in real-time (up to 20X in practice) for realizing reconfigurable multiband/mode radios in (sub)-mm-Wave frequency bands. His UCLA Lab also realized the first CMOS Frequency Synthesizer for Terahertz operation (PLL at 560GHz) and devised the first tri-color CMOS active imager at 180-500GHz based on a Time-Encoded Digital Regenerative Receiver and the first 3-dimensional SAR imaging radar with sub-centimeter range resolution at 144GHz. More recently, his Lab has devised a Reconfigurable Convolution Neuron Network (RCNN) Accelerator for IoT applications, spun-off an Edge-AI startup company Kneron in San Diego, and won IEEE’s 2021 Darlington Best Paper Award.
He is a Member of the US National Academy of Engineering, the European Academy of Sciences and Arts, the US National Academy of Inventors, the Academia Sinica of Taiwan, and a Fellow of the IEEE. He was also recognized with the IEEE David Sarnoff Award (2006), IET JJ Thomson Medal for Electronics (2017) and IEEE/RSE James Clerk Maxwell Medal (2023) for his seminal contributions to the heterojunction technology and realizations of (sub)-mm-Wave System-on-Chip with unprecedented bandwidth and re-configurability.
