Recent years witness active and extensive research activities in the development of mm-wave circuits and systems in CMOS technologies for a variety of applications, including communications, sensing, radar and imaging. To enable the wide deployment of mm-wave circuits and systems, critical components/sub-systems with high performance and power efficiency are demanded. Our group has also been actively investigating high performance mm-wave integrated circuits and systems for the past decade.
Figure above selects mm-wave circuits and systems developed by our group recently. We have demonstraed the first integrated CMOS passive imager with the NETD (Noise Equivalent Temperature Difference) of < 2K and the best noise equivalent power NEP of 26 fW/√Hz, the power efficiency of 25.9% for the CMOS signal generator and 10.6% for the CMOS transmitter, the record efficiency for CMOS signal generators/transmitters with the operating frequency > 150GHz, the first CMOS THz signal generator. The invented on-chip transformer based inter-stage coupling and matching scheme has been widely adopted in today’s mm-wave integrated circuits.
