Abstract: The next generation Internet of Things (IoT) envisions trillions of miniature devices that essentially disappear into the environment and objects around us, to improve our lives by measuring information from our world and routing it to stake-holders or connected devices that take action for our benefit. This talk describes how low power circuit design can enable this vision of a trillion-node IoT. Low power circuits for digital logic and memory operating in near-threshold or sub-threshold pair with system components from regulators to radios to enable ubiquitous computing that can operate continuously. In the extreme, these devices can operate entirely from harvested energy with no batteries required. This talk covers key tradeoffs for ultra-low power system design and describes several generations of systems-on-chip that have enabled self-powered system operation, which show active power consumption from microwatts to nanowatts. Together, these results provide a capability for designing ultra-low power wireless nodes to enable robust self-powered system deployments.
Bio: Benton H. Calhoun is the Alice M. and Guy A. Wilson Professor in the Electrical and Computer Engineering Department at the University of Virginia. He received his B.S. degree in electrical engineering from the University of Virginia, Charlottesville, VA, in 2000. He received the M.S. degree and Ph.D. degree in electrical engineering from the Massachusetts Institute of Technology, Cambridge, MA, in 2002 and 2006, respectively. His research has emphasized energy efficient and sub-threshold circuit design for self-powered, batteryless wireless sensing systems. Dr. Calhoun is a co-author of Sub-threshold Design for Ultra Low-Power Systems (Springer, 2006), author of Design Principles for Digital CMOS Integrated Circuit Design (NTS Press, 2012), and has over 270 peer reviewed publications and 30 issued US patents that contribute to the field of energy efficient circuits and systems for self-powered and energy constrained applications. He co-founded Everactive, Inc., which is selling self-powered, energy harvesting wireless sensing solutions in the industrial IoT market. He is a Fellow of the IEEE and a Senior Member of the National Academy of Inventors.
