The papers cover topics of CMOS tri-color mm-wave imaging receiver, 135-150GHz transmitter, D-band frequency synthesizer, and 200GHz 16-pixel focal plane array imager.
David Murphy's paper "A Blocker-Tolerant Wideband Noise-Cancelling Receiver with a 2dB Noise Figure" is recognized as ISSCC 2012 Distinguished Technical Paper Award (Best Paper Award in ISSCC). The technique proposed in the paper breaks the traditional noise/linearity trade-off inherent in all modern receivers, and is applicable to both software-defined radios and to receivers targeting current wireless standards. The co-authors include scientists in Broadcom, Prof. Frank Chang and Prof. Abidi in UCLA. The award will be presented at ISSCC 2012 on February 20 in San Francisco. Congratulations!
