ABSTRACT  |  The deployment of mm-wave portion of frequency spectrum (30 GHz to 300 GHz) for wireless applications is gaining tremendous popularity. The availability of wide bandwidth at the lower mm-wave bands (near 30 GHz, 60 GHz, etc.) makes these bands attractive for next generation mobile network. A key challenge in most CMOS communication systems operating at 60 GHz band and beyond is synthesis of on-chip LO frequency with high spectral purity, and large tuning range.

The upper mm-wave (200GHz and higher) and sub-THz bands are also attractive for applications such as medical imaging, non-invasive industrial testing and spectroscopy. Although CMOS promises a low-cost, portable platform for these applications, efficient power generation at these high frequencies faces daunting challenges on several fronts. This talk will describe the challenges in mm-wave clock generation using bulk CMOS processes and highlight some of our recent work on voltage controlled oscillators to address those challenges.

Bio  |  Sudip Shekhar received the B.Tech. degree (Hons.) from the Indian Institute of Technology, Kharagpur, and the M.S. and Ph.D. degree from the University of Washington, Seattle.

From 2008 to 2013, he was a Senior Research Scientist with Intel Labs, OR. He is currently an Assistant Professor of ECE at the University of British Columbia, Vancouver, Canada. His research interests include circuits for high-speed electrical and optical I/O interfaces, frequency synthesizers, and wireless transceivers.

Dr. Shekhar was a recipient of the IEEE Transactions on Circuits and Systems Darlington Best Paper Award in 2010 and a corecipient of IEEE Radio-Frequency IC Symposium Best Student Paper Award in 2015.
