Scaling Analog and RF Circuits: How and Why

POB 2.402

CMOS technology scaling has fueled tremendous progress in electronics and has brought about system-on-chip (SoC) products with a broad impact on our society and economy. Technology scaling is very beneficial to increase the performance and density for digital signal processing, computation and memory. Analog and radio-frequency (RF) circuits remain the critical interfaces to connect the digital cores of SoCs to the physical world and need to satisfy increasing performance demands.  At the same time, designing analog and RF functions with scaled devices and reducing supply voltages is getting progressively harder. Meeting more stringent performance requirements with poorer analog devices makes the task of the analog designer very challenging and interesting. We will review scaling challenges for analog circuit performance and contrast them to digital circuit scaling. We will further discuss design paradigms that address analog and RF circuit scaling, including mixed-domain analog techniques. The talk will also touch upon the novel application opportunities that scaled CMOS technologies enable. We will illustrate how exploiting high speed transistors can enable ultra-low power wireless communications for applications such as building an Internet of Things with energy harvesting active networked tags.

Professor Peter R. Kinget finished a dual electrical and mechanical engineering degree and a PhD degree in electrical engineering from the Katholieke Universiteit Leuven, Belgium, in 1990 and 1996, respectively. From 1996 to 1999, he was at Bell Laboratories, Lucent Technologies, in Murray Hill, NJ, as a Member of Technical Staff in the Design Principles Department. From 1999 to 2002 he held various technical and management positions in IC design and development at Broadcom, CeLight and MultiLink.

In 2002, he joined the faculty of Columbia University. His research interests are in analog, RF and power integrated circuits and the applications they enable in communications, sensing, and power management. Dr. Kinget is a Fellow of the IEEE. He has been a "Distinguished Lecturer" for the IEEE Solid-State Circuits Society. He is a co-recipient of the "Best Student Paper Award - 1st Place" at the 2008 IEEE Radio Frequency Integrated Circuits (RFIC) Symposium, of the "First Prize" in the 2009 Vodafone Americas Foundation Wireless Innovation Challenge, of the "Best Student Demo Award" at the 2011 ACM Conference on Embedded Networked Sensor Systems (ACM SenSys), of the "2011 IEEE Communications Society Award for Advances in Communication" for an outstanding paper in any IEEE Communications Society publication in the past 15 years, and of the "First Prize ($100K)" in the 2012 Interdigital Innovation Challenge (I2C).
