Key elements in an millimeter-wave frequecy transceiver front-end, from system to transistor-level circuits are outlined in this lecture. An overview of phased-array receiver architectures is presented, showing how signal combining may be implemented in the front-end, after mixing, or at baseband. Transceiver circuit examples include: neutralization, noise canceling wideband amplifiers, switching mixers used in
mixer-first receivers, optimization of on-chip tank-Q and LC-voltage-controlled oscillators, and the Doherty scheme for efficiency improvement in RF power amplifiers.

Speaker Biography
John R. Long received the B.Sc. in Electrical Engineering from the University of Calgary in 1984, and the M.Eng. and Ph.D. degrees in Electronics from Carleton University, Ottawa, Canada, in 1992 and 1996, respectively. He worked for 12 years in the Advanced Technology Laboratory at Bell-Northern Research in Ottawa, and then began his academic career at the University of Toronto (1996-2002). From 2002-2014 he was Chair of the Electronics Research Laboratory at TU Delft in the Netherlands. He has been a faculty member in the Department of Electrical and Computer Engineering at the University of Waterloo since 2015. His current research interests include low-power and broadband circuits for highly-integrated wireless transceivers, energy-efficient wireless sensors, and IC design for mm-wave and high-speed data communication.
