Future Role of Mixed-Signal Circuits for Energy-Efficient Communication Systems
System integrated circuit (IC) design is the key step to move forward to next-generation wireless communication systems where low-power transceivers, secure connectivity, and energy-efficient high-speed links all matter. As system ICs with advanced CMOS technology demand not only low-power but also low-voltage design, matching and linearity problems in the design of mixed-signal circuits have become more critical than ever. In this talk, the importance of building strong mixed-signal circuit IPs with innovative circuit design is addressed for frequency modulation, demodulation, fine ranging, and energy-efficient transmission. Then, ultra-wideband (UWB) transceivers based on novel mixed-signal circuits are presented for mobile authentication, in-vehicle infotainment (IVI), brain-computing interface (BCI), and real-time location applications.

Biography:
Woogeun Rhee received the B.S. degree in electronics engineering from Seoul National University, Seoul, Korea, in 1991, the M.S. degree in electrical engineering from the University of California, Los Angeles, CA, USA, in 1993, and the Ph.D. degree in electrical and computer engineering from the University of Illinois, Urbana-Champaign, IL, USA, in 2001. From 1997 to 2001, he was with Conexant Systems, Newport Beach, CA, USA. From 2001 to 2006, he was with IBM Thomas J. Watson Research Center, Yorktown Heights, NY, USA. He was a Visiting Professor at Seoul National University, Korea, from August 2022 to February 2023. He is currently a Professor with the School of Integrated Circuits, Tsinghua University, China. He has published more than 180 IEEE papers and holds 24 U.S. patents.
He currently serves on the AdCom of the IEEE SSCS and the BoG of the IEEE CASS as an SSCS Representative. He also serves as the Editor-in-Chief for OJ-SSCS. He was an SSCS Chapters Steering Committee Member from 2021 to 2023, a Distinguished Lecturer from 2016 to 2017, an Associate Editor for OJ-SSCS from 2021 to 2023, JSSC from 2012 to 2018, TCAS-II from 2008 to 2009, and a Guest Editor for JSSC Special Issue in November 2012, November 2013, and October 2022. He has served on the Technical Program Committees for IEEE conferences, including ISSCC, CICC, and A-SSCC. He was the TPC Chair of A-SSCC 2021 and has been the Steering Committee Member of A-SSCC. He is an IEEE Fellow.
