Abstract: Clocks play a central role in IoT devices. Apart from their typical use in communications, localization, timing mixed-signal and digital logic units etc., they also serve as an always-ON time-keeper and provide timing for aggressive duty cycling of power-hungry blocks. The last two use cases have a great impact on overall system energy consumption of several IoT devices, and require clocks that are simultaneously stable and consume low energy. This talk will describe two recent techniques that lower energy consumption in stable crystal oscillators: one via quick startup of the XO and the other via a very low energy sustaining circuit.
Biography: Dr. Sudhakar Pamarti is a Professor of Electrical and Computer Engineering at the University of California, Los Angeles. He received the Bachelor of Technology degree from the Indian Institute of Technology, Kharagpur in 1995, and M.S. and Ph.D. degrees in electrical engineering from the University of California, San Diego in 1997 and 2003 respectively. He has either worked for, consulted with, or advised both software and hardware companies such as Hughes Software Systems, Rambus Inc., SiTime, Alterra, FemtoDx etc. on various aspects of wireless and wireline communications, and analog, mixed-signal, and RF integrated circuit (IC) design.
His research focuses on developing various techniques, especially signal processing ones, to overcome common impairments in ICs. This includes both establishing the theoretical basis of such techniques as well as demonstrating their efficacy using record setting prototype ICs. Dr. Pamarti is a recipient of the National Science Foundation’s CAREER award. He currently serves on the technical program committees of CICC and ISSCC, as a Solid State Circuits Society Distinguished Lecturer, and has, in the past, served as an Associate Editor for both Parts I and II of the IEEE Transactions on Circuits and Systems, and as a Guest Editor for the IEEE Journal of Solid-State Circuits.
