Our speaker was  Cristian Marcu (Berkeley Wireless Research Center), and the topic of his presentation was  ” A Low-Power 60GHz Transceiver with Integrated Baseband Circuitry”

Abstract

With mobile devices becoming more powerful and including more storage than ever before, new applications are emerging that require fast wireless data transfers while consuming very low power. This talk will present the key design techniques and challenges in implementing a low power 90nm CMOS 60GHz transceiver that includes RF, LO, PLL and BB integrated into a single chip. With a 1.2V supply the chip consumes 170mW while transmitting 10dBm and 138mW while receiving. Data transmission up to 5Gbps on each of I and Q channels has been measured, as has data reception over a 1m wireless link at 4Gbps QPSK with less than 10-11 BER.

Biography

Cristian Marcu (S’01) received the B.S.E.E. degree from the University of California, Irvine, in 2005 and the Masters degree in electrical engineering from the University of California, Berkeley, in 2008. He is currently pursuing the Ph.D. degree in electrical engineering at the University of California, Berkeley.

In 2007, he was with Qualcomm Inc. in Campbell, CA, working on cellular receivers. His research interests include CMOS mm-wave circuit design, and low power frequency synthesis for mm-wave applications.
