Ultra-wideband Millimeter-wave Integrated Circuits for 5G Communications and Beyond

Speaker: Jeyanandh Paramesh, CMU

Abstract:
The demand for wireless capacity and data rates continues to grow unabated. In order to meet this demand, future communication systems will incorporate a mix of new techniques at all layers of the network. At the physical layer, these include reconfigurable spectrum sharing radios in the low GHz bands, and (sub)mm-wave radios. In both types of systems, the need to support very wide bandwidths and massively large numbers of antennas in an energy efficient manner is of paramount importance. In this talk, I will describe our recent research aimed at addressing these challenges. In particular, we will describe design techniques for energy efficient beamformers, digital frequency synthesizers and mixed-signal interfaces for such systems. I will also briefly describe recent developments in CMU’s long standing research on the reconfiguration of RF integrated circuits using phase-change switches, which we envision as a “more-than-Moore” element that can augment the capabilities of standard CMOS technologies.

Biography:
Jeyanandh Paramesh received the B.Tech, degree from IIT, Madras, the M.S degree from Oregon State University and the Ph.D degrees from the University of Washington, Seattle, all in Electrical Engineering. He is currently Associate Professor of Electrical and Computer Engineering at Carnegie Mellon University. He has held product development positions with Analog Devices, where he designed high-performance data converters, and Motorola where he designed analog and RF integrated circuits for cellular transceivers. From 2002 to 2004, he was with the Communications Circuit Lab, Intel where he developed multi-antenna receivers, high-efficiency power amplifiers and high-speed data converters high data-rate wireless transceivers. His research broadly addresses design and technological challenges related to RF and mixed-signal integrated circuits and systems for emerging applications.
