Woogeun Rhee is a Professor in the Institute of Microelectronics and the Department of Microelectronics and Nanoelectronics at Tsinghua University, Beijing, China. He has over 20 years of professional career in integrated circuit design with nearly 10 years in industry and 13 years in academia. From 1997 to 2001, he was with Conexant Systems, Newport Beach, CA, where he developed a low-power low-cost fractional-N frequency synthesizer product. From 2001 to 2006, he was with IBM Thomas J. Watson Research Center, Yorktown Heights, NY and worked on clocking circuits for high-speed I/O serial links, including low-jitter phase-locked loops, clock-and-data recovery circuits, and on-chip testability circuits. He has published ›150 IEEE publications and currently holds 24 US patents. He is an IEEE Distinguished Lecturer (2016-2017) and an Ex-Officio Administrative Committee (AdCom) member of the Solid-State Circuits Society (2020).
