Our speaker was  Ali M. Niknejad (EECS department at UC Berkeley), and the topic of his presentation was
” The Road to 60 GHz Wireless CMOS”

ABSTRACT:
Commercial CMOS chips routinely operate up to 5 GHz and exciting new opportunities exists in higher frequency bands such as 3-10 GHz, 17 GHz, 24 GHz, and 60 GHz. The Berkeley Wireless Research Center (BWRC) has demonstrated that standard digital 130nm CMOS technology is capable of operation up to 60 GHz, enabling a host of new mm-wave applications such as Gb/s WLAN and compact radar imaging. How did we go from 5 GHz to 60 GHz? This presentation will highlight the design and modeling challenges in moving up to these higher frequencies. A merger of RF and microwave design perspectives will be used to offer insight into the problem. The architecture for a 60 GHz multi-antenna phased array will be discussed, enabling a low cost robust high data rate system to be integrated into a compact package.

BIO:
Ali M. Niknejad received the B.S.E.E. degree from the University of California, Los Angeles, in 1994, and his Master’s and Ph.D. degrees in electrical engineering from the University of California, Berkeley, in 1997 and 2000. After graduation from Berkeley he spent two years in industry designing analog RF integrated circuits and devices for wireless communication applications. Presently he is an assistant professor in the EECS department at UC Berkeley. He is an associate editor for the Journal of Solid-State Circuits. Prof. Niknejad is a BWRC faculty member and co-director of the BSIM project. His current research interests lie within the area of circuits for wireless and broadband communications. This includes implementation of integrated communication systems in silicon, device compact modeling, computer-aided design and optimization of such systems, and numerical techniques in electromagnetics particularly as applied to the analysis and modeling of active and passive devices at microwave frequencies.
