Solid-State Circuits Society PRESENTATION: Wireless Powering for Ultra Low Power Batteryless IoT Sensing and Communication

DATE October 25, 2018 BIOGRAPHY Dr. Natarajan’s research is focused on RF and mm-wave integrated circuits and sys- tems for wireless communication and imaging. He TIME Lunch at 12 noon, presentation from 12:30 received the B.Tech. degree in electrical engineering to 2:00 p.m. from the Indian Institute of Technology, Madras, in 2001 and the M.S. and Ph.D. degrees in electrical en- LOCATION USU Flintridge Room, California gineering from the California Institute of Technology State University, Northridge (Caltech), Pasadena, in 2003 and 2007, respectively.
