Distinguished Lecture: On-Chip Self-Interference Cancellation for Full Duplex Radios and Other Applications

Several efforts of the last decade have demonstrated the ability of a radio transceiver to simultaneously transmit and receive using the same frequency band – this is commonly referred to as in-band full duplex communication.

This presentation will explore similarity and differences between the problem of self-interference/signal cancellation in very diverse applications from the perspective of noise, linearity, cancellation bandwidth, convergence of adaptation algorithms and suppression depth. Two examples of integrated self-interference cancellation will be presented (i.e., for neural interfaces and wireless communication) that define the state-of-the-art with respect to linearity, noise and the ability to adapt on-chip cancellation filters in real time.

Prof. Chris Rudell


On-Chip Self-Interference Cancellation for Full Duplex Radios and Other Applications


Jacques Christophe “Chris” Rudellreceived degrees in electrical engineering from the University of Michigan (BS), and UC Berkeley (MS, PhD). After finishing his PhD, he worked for several years as an RF IC designer at Berkana Wireless (now Qualcomm) and Intel Corporation.  In January 2009, he joined the University of Washington, Seattle, where he is now an Associate Professor of Electrical and Computer Engineering. He is also a member of the Center for Neural Technology (CNT) and co-director of the Center for Design of Analog-Digital Integrated Circuits (CDADIC).

While a PhD student at UC Berkeley, Dr. Rudell received the Demetri Angelakos Memorial Achievement Award, a citation given to one student per year by the EECS department. He has twice been co-recipient of the best paper awards at the IEEE International Solid-State Circuits Conference, the first of which was the 1998 Jack Kilby Award, followed by the 2001 Lewis Winner Award. He received the 2008 ISSCC best evening session award, and best student paper awards at the 2011 and 2015 RFIC Symposium. Chris is the recipient of the National Science Foundation (NSF) CAREER Award. He served on the ISSCC technical program committee (2003-2010) and on the IEEE Radio Frequency Integrated Circuits (RFIC) Symposium steering committee (2002-2013), where he was the 2013 General Chair. He was an Associate Editor for theIEEE Journal of Solid-State Circuits (2009-2015). At present, he serves on the technical program committees of the IEEE European Solid-State Circuits Conference(ESSCirC) and the IEEE Custom Integrated Circuits Conference (CICC).
