Abstract: Operation in the mm-wave frequency range has gained renewed interest due to abundance of unutilized spectrum. If combined with spectrally efficient (de-)modulation techniques, mm-wave wireless communication has the potential to achieve multi-gigabit-per-second wireless data-rate. In addition, the operation at higher frequency gives rise to smaller sized passive components (most notably antennae), making it possible to design and implement massive phase-array or MIMO systems on a single die or single wafer. As the communication schemes including spectrally-efficient (de-)modulation and carrier aggregation techniques are making progress at RF frequencies, far more challenging requirements will be imposed on the oscillator and frequency synthesis design. Increasing the carrier frequency towards the mm-wave regime only makes these requirements more stringent. This webinar intends to provide a general, yet in depth, overview of frequency generation and synthesis at mm-wave frequencies. First, the fundamentals of oscillator design at mm-wave frequencies will be revisited and the performance of a number of basic oscillator topologies in terms of phase-noise and minimum gain requirement for oscillation start-up will be compared. Along the way, several oscillator topologies (which are amenable to high frequencies) including modified Clapp, double-stacked cross-coupled pair, inductive tuning, and varactor tuning with loss compensation will be introduced. The webinar talk will then present mm-wave frequency generation using lower-frequency PLLs followed by frequency multipliers, and make a case in favor of this technique to be employed for large transceiver arrays. Finally, a new perspective and design philosophy of mm-wave/THz frequency synthesizer design for the purpose of maximizing output power and frequency tuning and minimizing phase-noise will be provided.
Payam Heydari received his B.S. and M.S. degrees in Electrical Engineering from Sharif University of Technology in 1992 and 1995, respectively. He received his Ph.D. degree from the University of Southern California in 2001. He is currently a Full Professor of Electrical Engineering at the University of California, Irvine.
During the summer of 1997, he was with Bell-labs, Lucent Technologies where he worked on noise analysis in high-speed CMOS integrated circuits. He worked at IBM T. J. Watson Research Center on gradient-based optimization and sensitivity analysis of custom analog/RF ICs during the summer of 1998. His research covers the design of terahertz/millimeter-wave/RF and analog integrated circuits. He is the (co)-author of two books, one book chapter, and more than 120 journal and conference papers. He has given Keynote Speech to IEEE GlobalSIP 2013 Symposium on Millimeter Wave Imaging and Communications and served as Invited Distinguished Speaker to the 2014 IEEE Midwest Symp. on Circuits and Systems. He was the Distinguished Lecturer of IEEE Solid-State Circuits Society.
Dr. Heydari is recipient of the Distinguished Engineering Educator Award from Orange County Engineering Council. The Office of Technology Alliances at UCI has named Dr. Heydari one of 10 Outstanding Innovators at the university. He is the co-recipient of the 2009 Business Plan Competition First Place Prize Award and Best Concept Paper Award both from Paul Merage School of Business at UC-Irvine. He is the recipient of the 2010 Faculty of the Year Award from UC-Irvine's Engineering Student Council (ECS), the 2009 School of Engineering Best Faculty Research Award, the 2007 IEEE Circuits and Systems Society Guillemin-Cauer Award, the 2005 IEEE Circuits and Systems Society Darlington Award, the 2005 National Science Foundation (NSF) CAREER Award, the 2005 Henry Samueli School of Engineering Teaching Excellence Award, and the Best Paper Award at the 2000 IEEE Int'l Conference on Computer Design (ICCD). He was recognized as the 2004 Outstanding Faculty in the EECS Department of the University of California, Irvine. His research on novel low-power multi-purpose multi-antenna RF front-ends received the Low-Power Design Contest Award at the 2008 IEEE Int'l Symposium on Low-Power Electronics and Design (ISLPED).
Dr. Heydari currently serves on the Technical Program Committee of the International Solid-State Circuits Conference (ISSCC).
