Résumé: There has been significant recent progress towards the realization of multi-Gbps optical receivers fully integrated into standard CMOS processes. Consider how the emergence of CMOS image sensors in the 90's revolutionized and proliferated digital cameras. Likewise, CMOS photodetectors enable highly-integrated, compact, and low cost optical receivers opening up new applications for multi-Gbps optical links in data centers, consumer electronics, and automotive. Past work on has focused on using the pn-junctions and depletion regions available in a standard CMOS process to eliminate, minimize, or cancel the slowly diffusing photocarriers that usually limit the bandwidth of CMOS photodetectors. However, if considered simply as a form of ISI, the slowly diffusing carriers can be dealt with using the same signal processing tools in wide use for other wireline communication applications, including decision feedback equalization. A combination of spatially-modulated light detection, analog equalization, and modest decision feedback equalization appears to offer a path towards data rates in excess of 10-Gbps using integrated photodetectors. Nanoscale CMOS is particularly well suited to the implementation of such signal processing functions.

Note biographique: Tony Chan Carusone completed the B.A.Sc. and Ph.D. degrees at the University of Toronto in 1997 and 2002 respectively. Since 2001, he has been with the Department of Electrical and Computer Engineering at the University of Toronto where he is currently an Associate Professor. He has been a visiting researcher at the University of Pavia, Italy and at the Circuits Research Lab of Intel Corp., Hillsboro, Oregon. Prof. Chan Carusone was a co-author of the best student papers at both the 2007 and 2008 Custom Integrated Circuits Conferences and the best paper at the 2005 Compound Semiconductor Integrated Circuits Symposium. He serves on the technical program committees of the International Solid-State Circuits Conference and the VLSI Circuits Symposium, and in the past served on the technical program committee of the Custom Integrated Circuits Conference. He served on the editorial board of the IEEE Transactions on Circuits and Systems II: Express Briefs from 2006 until 2009 when he was Editor-in-Chief, and is now an associate editor for the IEEE Journal of Solid-State Circuits.
