Abstract

This presentation will highlight several projects including our existing efforts on integrating systems for neural interface applications, ultra-broadband mmWave transceiver circuits, and radio front-ends for in-band full duplex communication. A  description of four separate integrated transceivers that include self-interference cancellation methods for full duplex radio operation, the two most recent of which report(ed) at the 2017 and 2018 ISSCC, achieve state-of-the-art performance with respect to self-interference cancellation depth and bandwidth. This will be followed by an overview of our work on ultra-broad mm-Wave transceivers. Time permitting, a discussion will be given on high-integration neural stimulators for Bidirectional Brain Computer Interfaces (BBCI) chips. Specifically, a CMOS neural stimulator IC that achieves a +/-12V voltage compliance with a 2mA peak current to drive a wide variety of electrode impedances. This presentation will conclude with some thoughts on artifact cancellation in neural stim-sense interfaces, and the uncanny relationship to the problem of transmitter self-interference cancellation in full duplex radio systems.

Speaker Bio

Jacques “Chris”tophe Rudell received degrees in electrical engineering from the University of Michigan (BS), and UC Berkeley (MS, PhD). After completing his degrees, he worked for several years as an RF IC designer at Berkana Wireless (now Qualcomm), and Intel Corporation.  In January 2009, he joined the faculty at the University of Washington, Seattle, where he is now an Associate Professor of Electrical Engineering. He is also a member of the Center for Sensorimotor Neural Engineering (CSNE).

 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 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 & 2015 RFIC Symposium best. Chris is recipient of the National Science Foundation (NSF) CAREER Award. Dr. Rudell served on the ISSCC technical program committee (2003-2010), and on the MTT-IMS Radio Frequency Integrated Circuits (RFIC) Symposium steering committee (2002-2013), where he was the 2013 General Chair. He was an Associate Editor for the Journal of Solid-State Circuits (2009-2015).
