Title: Ultra-low Power Circuit Design Techniques for Low Power IoT and Biomedical Systems

Abstract: Wearable electronics, intelligent devices, medical electronics, and more recently Internet of Things (IoTs) are dramatically changing the way we experience life by providing rich information about our activities, health, and the environment. To be truly ubiquitous, these devices must be energy autonomous. Such a system must harvest energy from ambient sources like light, RF, temperature differentials, etc. and must also be very efficient in using the little energy available to it for computation. This talk focuses on how to enable perpetual, self-sustaining ultra-low power systems particularly in the context of emerging circuits and system design techniques. We will discuss circuits that can harvest energy efficiently from the smallest ambient sources, and ultra-low power analog and mixed signal circuits for computing, and implementation of fully analog systems. The talk also focusses on hardware security challenges for Ultra-low power systems and mitigation techniques.

Bio: Aatmesh Shrivastava received the B.E. degree in electronics and communication engineering from Birla Institute of Technology, Ranchi, India in 2006 and the Ph.D. degree in electrical engineering from the University of Virginia, Charlottesville, VA, in 2014.

From 2006 to 2010, he worked as a Sr. Design Engineer at Texas Instruments in Bangalore. From 2010 to 2014, he worked as a Research Assistant with the Robust Low Power VLSI group at the University of Virginia. From 2014 to 2016, he worked as a Sr. Design Director at an IoT start-up, Everactive in Charlottesville, VA. Since 2016, he has been working as an Assistant Professor with the Electrical and Computer Engineering Department at Northeastern University in Boston. His research interests include self-powered and ultra-low power circuits and system, hardware security, energy-harvesting system, analog computing, and hardware for AI. He serves an editor for IEEE Open Journal on Circuits and Systems (OJCAS) and on the Editorial Review Board of IEEE Solid-State Circuits Letters (SSCL) as well as on on the technical program committee of several conferences including, DAC, ISCAS, MWSCAS, ISLPED, ICCD, etc.
