Capacitive Sensor Interfaces - Man-Kay Law | ISSCCedu 2020

Abstract: Capacitive sensors for displacement, proximity and pressure sensing are widely deployed in various consumer, medical, automotive, and industrial sectors, with the advantages of zero static power consumption and good compatibility with CMOS circuitry. This tutorial provides an overview of the fundamental principles of capacitive sensor interfaces, as well as the design tradeoffs in terms of accuracy and energy consumption. Recent techniques to achieve low-noise and high-efficiency sensing will also be discussed. Bio: Man-Kay Law received the B.Sc. degree in Computer Engineering and the Ph.D. degree in Electronic and Computer Engineering from Hong Kong University of Science and Technology. Since 2011, he has been with the State Key Laboratory of Analog and Mixed-Signal VLSI, University of Macau, Macau, China, where he is currently an Associate Professor. His research interests include ultra-low-power sensing circuits and systems, analog and mixed-signal integrated circuits, and energy harvesting techniques. He is a co-recipient of the A-SSCC Distinguished Design Award in 2015, and also the advisor for student awards, including the SSCS Pre-doctoral Achievement Award and the ISSCC Silk-Road Award. He is a member of the Technical Program Committee of ISSCC.
