Major Research Areas
Ultrawide Band (UWB) Transceivers, Optical Communication Circuits, Phase-Locked Loops, and Data Converers.
Research Summary
Dr. Lee's research interests include broadband data communication circuits, wireless transceivers, phase-locked loops and low-noise broadband amplification, A/D and D/A converters, and modeling of passive and active devices in deep-submicron CMOS technologies.
Jri Lee (M’ 03) received the B.Sc. degree in electrical engineering from National Taiwan University, Taipei, Taiwan, in 1995, and the M.S. and Ph.D. degrees in electrical engineering from the University of California, Los Angeles (UCLA), both in 2003.
From 1997 to 1998, he was with Academia Sinica, Taipei, Taiwan, investigating control systems for novel solid-state lasers. From 2000 to 2001, he was with Cognet Microsystems, Los Angeles, CA, and subsequently with Intel Corporation, where he worked on SONET OC-192 and OC-48 transceivers. Since 2004, he has been Assistant Professor of electrical engineering at National Taiwan University. He is currently serving on the Technical Program Committees of the International Solid-State Circuits Conference (ISSCC) and Asian Solid-State Circuits Conference (A-SSCC). His research interests include broadband data communication circuits, wireless transceivers, A/D and D/A converters, phase-locked loops and low-noise broadband amplification, and modeling of passive and active devices in deep-submicron and nanometer CMOS technologies.
