"Compact Silicon Integrated mmWave Circuits: From Skepticism to 5G and Beyond"
Silicon integration of millimeter wave (mmWave) circuits began with early investments from DARPA almost 20 years ago, with the DARPA TEAM (Technology for Efficient Agile Microelectronics) program. By convincing skeptics that mmWave circuits, traditionally implemented using discrete III-V blocks, could function reliably when fully integrated into silicon-based SiGe and CMOS processes, this technology has broadly evolved across today’s highly integrated systems. The development of comprehensive CMOS and SiGe PDK (Process Development Kit) and the supporting modeling and design infrastructure provided a viable path for circuit designers to adopt this technology.
The tremendous volume reduction of ~1000X coupled with a ~1000X increase in integration complexity brought about by silicon-integration has already enabled the first generation of mmWave commercial automotive radar and data communication products, and placed mmWave as a key component of the next global mobile communications standard - 5G. This level of multi-antenna mmWave system sophistication was unimaginable a decade ago.
This talk will review the journey of mmWave technology over the last two decades, and outline the possibilities of a future where multi-functional mmWave circuits are a key differentiator in vertically integrated "Antennas to AI" cognitive systems.

"The road ahead for autonomous cars – what’s in for RFIC"
Our cars are morphing into connected, self-driving “robots” that can sense the environment, think and act autonomously. Today’s cars are loaded with technologies that enable new in-vehicle experiences or safety and automation applications like advanced driver assistance systems (ADAS). Connectivity is ultimately redefining the way cars are conceptualized and built. In cars of the future, all of the interfaces – radio, cellular, WiFi, Bluetooth, GPS, vehicle-to-everything (V2X) communications, and more – can be integrated into a single, secure smart antenna that serves as both a transmitter and receiver of communications with a variety of channels, standards, and bandwidths. However, various wireless technologies can also introduce cyber security risks. As the car becomes a hub of connectivity, it opens potential attack opportunities for hackers. How secure can a fully connected car be? What should future car architectures look like to enhance security? How will RFIC technology and connectivity transform the driving experience of tomorrow and what are the next big innovations to expect?
