CONFÉRENCE CHAPITRE CAS/EMB: CMOS circuits for compact energy-efficient optical receivers


Optical links are widely deployed in data centres and other high-performance computing applications, with increasing demand for high-speed, low-power designs occupying a small die footprint. This talk presents our work in inductor-less optical receiver design for data rates of up to 25 Gb/s. One emerging approach to lowering link power dissipation is to increase the receiver front-end’s gain at the expense of introducing significant inter-symbol interference (ISI). This talk will summarize the variety of equalization strategies that have been deployed to eliminate ISI along with our recent work.

Glenn Cowan of Dept of ECE, Concordia University


Glenn Cowan received the B.A.Sc. degree from the University of Waterloo, Waterloo, ON, Canada in 1999, and the M.S. and Ph.D. degrees from Columbia University, New York, NY, in 2001 and 2005, respectively. During his graduate studies, he interned with Philips Research, Briarcliff Manor, NY. In 2005, he joined the Communications Technology Department at the IBM T. J. Watson Research Center, Yorktown Heights, NY. His research activities included CMOS circuits for high-speed communications, design for manufacturability, and circuits for the measurement of process variability.

In 2007, he joined the Department of Electrical and Computer Engineering at Concordia University in Montreal, QC, Canada, where he is an Associate Professor. At Columbia, Dr. Cowan was a 2003 recipient of Analog Device’s Outstanding Student Designer Award. He was the 2005 recipient of Columbia’s Eliahu I. Jury award for outstanding achievement by a graduate student in the areas of systems, communications, or signal processing. His current research activities include low-power mixed-signal circuits for wireless, wireline, and optical communication, as well as mixed-signal computation.
