ABSTRACT:

While the 60GHz band has gained substantial attention over the last decade as a potential enabler for multi-Gb/s wireless connectivity over 3-5m range, substantial transceiver design challenges remain in terms of both energy-efficiency and cost. Specifically, for large phased arrays the power consumed by per-element overhead circuitry becomes dominant. Similarly, the costs of testing and packaging a 60GHz CMOS transceiver can easily dominate over the cost of the silicon die itself. In this talk I will describe some of our latest research to address these issues, highlighting both a methodology to choose the optimal number of antennas from a power consumption standpoint as well as a fully integrated (including on-chip antennas) 4-element 60GHz transceiver that achieves 10.2Gb/s in 115mW (TX+RX) with greater 0.4m range in all directions.

 

BIO:

 

Elad Alon received the B.S., M.S., and Ph.D. degrees in Electrical Engineering from Stanford University in 2001, 2002, and 2006, respectively. In Jan. 2007, he joined the University of California at Berkeley, where he is now an Associate Professor of Electrical Engineering and Computer Sciences as well as a co-director of the Berkeley Wireless Research Center (BWRC). He has held consulting or visiting positions at Cadence, Xilxin, Oracle, Intel, AMD, Rambus, Hewlett Packard, and IBM Research, where he worked on digital, analog, and mixed-signal integrated circuits for computing, test and measurement, and high-speed communications. Dr. Alon received the IBM Faculty Award in 2008, the 2009 Hellman Family Faculty Fund Award as well as the 2010 UC Berkeley Electrical Engineering Outstanding Teaching Award, and has co-authored papers that received the 2010 ISSCC Jack Raper Award for Outstanding Technology Directions Paper, the 2011 Symposium on VLSI Circuits Best Student Paper Award, and the 2012 Custom Integrated Circuits Conference Best Student Paper Award. His research focuses on energy-efficient integrated systems, including the circuit, device, communications, and optimization techniques used to design them.
