University of Toronto - Department of Electrical and Computer Engineering

The University of Toronto is Canada's top research university with an annual budget for research of 1.2B Canadian dollars in 2016. It is the only Canadian institution named in Times Higher Education's first-ever listing of top universities working with the world's most innovative companies. U of T ranked 18th in the world and 1st in Canada, one notch ahead of Johns Hopkins University and four above the University of Cambridge. U of T is known for its culture of innovation, research partnerships that span the globe, a diverse array of collaborations with private sector and public sector organizations, and a vibrant entrepreneurship culture supported by a network of campus-linked accelerators and incubators.

Founded in 1909, The Edward S. Rogers Sr. Department of Electrical & Computer Engineering (ECE) maintains a proud history of world-leading research and innovative education. We are the top-ranked ECE department in Canada and home to 100 professors, 649 graduate students and 1,513 undergraduates. In 2016, ECE was ranked 27th in the world and 11th in North America. Among our faculty members there are 28 Fellows of the IEEE, nine Fellows of the Royal Society of Canada, 13 Fellows of the Canadian Academy of Engineering, and four E.W.R. Steacie Fellows, a prize awarded to the brightest and most promising scientists and engineers across the country. ECE is a hotbed of research commercialization, with more than 160 inventions disclosed and 47 patents filed over the past five years-by far the most productive department for new inventions at the University of Toronto.

The VLSI Research Group led by Professor Sorin P. Voinigescu carry out leading research on novel electronic devices, THz and photonics systems on chip (SoCs), to demonstrate their commercial viability and new applications for nano-electronics, new products, new companies and wealth creation. The main applications are in telecommunications, radiometry, radio astronomy, high-resolution imaging, industrial, remote, and environmental sensing. Current research themes are: atomic-scale electronic devices and ICs for silicon quantum computing; THz sampling techniques for analog and mixed-signal processing; mm-wave radios, sensors, radars and imagers; and energy-efficient Tb/s photonic transceivers.

Sorin P. Voinigescu received the MSc degree in Electronics from the Polytechnic Institute of Bucharest, Romania, in 1984 and the PhD degree in Electrical and Computer Engineering from the University of Toronto, in 1994. Since 2002 he has been with the Electrical and Computer Engineering Department at the University of Toronto, where he is a Professor. His research and teaching interests focus on atomic-scale electronic devices and their application in integrated circuits and Systems-on-Chip at frequencies beyond 300 GHz.

He is the author of several frequently-cited papers on Si and SiGe microwave and mm-wave devices and integrated circuits, and of a well-regarded book on High-Frequency Integrated Circuits published by Cambridge University Press in 2013. In 2008-2009 and 2015-2016 he spent sabbatical leaves at Fujitsu Laboratories of America, Sunnyvale, CA, USA, at NTT's Device Research Laboratories in Atsugi, Japan, at Robert Bosch GmbH in Germany, and at UNSW in Sydney, where he conducted research on technologies and circuits for mm-wave radio, radar and sensors, and on 1Tb/s fiber-optic systems. In 2009-2010 he co-founded and was the CTO of Peraso Technologies which commercializes mm-wave radio WiGig and backhaul transceivers. In 2000, Dr. Voinigescu co-founded and was the CTO of Quake Technologies in Ottawa, Canada, which introduced the first commercial single-chip 10Gb/s SONET and 10GEthernet transceivers in 2001 and 2002, respectively, and which was acquired by AMCC in 2006 after 23 quarters of continuous revenue growth. Between 1994 and 2000 he was with NORTEL in Ottawa where he was responsible for projects in high-frequency characterization and statistical scalable compact model development for Si, SiGe and III-V devices. He also conducted research on wireless and optical fiber building blocks and transceivers in these technologies.

From 1984 through 1991 he worked as a microwave semiconductor device and circuits research engineer at the Research Institute for Electronic Components in Bucharest, and as Assistant Professor in the Electronics Department of the Polytechnic Institute of Bucharest. Dr. Voinigescu is a IEEE Fellow member of the ExCom of the IEEE BCICTS and TPC member of IEEE ESSCIRC, IEEE IMS and IEEE IEDM. He was a Guest Editor of the IEEE Journal of Solid State Circuits in 2015 and 2017, and of the IEEE Transactions on Microwave Theory and Techniques in 2012. From 2003 to 2013 he served on the TPC and ExCOM of the IEEE CSICS and was the Conference Chair in 2012. Between 2008 and 2015 he was a member of the RF/AMS committee of the ITRS. He received NORTEL's President Award for Innovation in 1996 and, in 2013, he was recognized with the ITAC Lifetime Career Award for his contributions to the Canadian Semiconductor Industry.
