Un-Ku Moon received the B.S. degree from the University of Washington, Seattle, in 1987, the M.Eng. degree from Cornell University, Ithaca, NY, in 1989, and the Ph.D. degree from the University of Illinois at Urbana-Champaign in 1994.

He has been with the School of Electrical Engineering and Computer Science, Oregon State University, Corvallis, since 1998. Before joining Oregon State University, he was with Bell Laboratories from 1988 to 1989, and from 1994 to 1998.

He is an IEEE Fellow and was awarded the National Science Foundation CAREER Award, the OSU Graduate Mentoring Award, and the OSU College of Engineering Engelbrecht Young Faculty Award and Research Award.

His current and past professional services include editor-in-chief of the IEEE Journal of Solid-State Circuits, distinguished lecturer of the IEEE Solid-State Circuits Society, editor-in-chief and deputy editor-in-chief of the IEEE Transactions on Circuits and Systems II, associate editor of the IEEE Journal of Solid-State Circuits and the IEEE Transactions on Circuits and Systems II, and Technical Program Committee of the IEEE International Solid-State Circuits Conference, the IEEE VLSI Circuits Symposium, and the IEEE Custom Integrated Circuits Conference. He also served on the IEEE Solid-State Circuits Society (SSCS) Administrative Committee and the IEEE Circuits and Systems Society (CASS) Board of Governors as the SSCS representative to CASS.

Research Interests

Research Areas
Analog and mixed-signal circuits including high-frequency and low-voltage switched-capacitor circuits, highly linear and tunable continuous-time filters, timing recovery, PLLs, data converters, and low voltage circuits for CMOS.

Research Background/Applications
While much attention and publicity is given to the digital side of electronics chips (e.g. personal computer boom in the 80s with Intel microprocessors, digital audio, digital mobile phones, etc.), the real-world interfaces of all these systems, such as microphones, speakers, computer modems, wireless receivers/transmitters, etc., remain primarily analog. This is simply because the real-world is analog. This reality gives people like me a lot of interesting research topics to pursue. Some of the most popular and important work in this area revolves around data conversion (analog-to-digital and digital-to-analog converters). And as the physical dimensions of transistors in ICs are getting smaller all the time, which implies more functionality, faster processing, more memory, etc., this also means analog circuits will have to work properly with these changes, including lower voltage supply. This turns out to be a challenging task, and this has been one of my main research thrusts here at Oregon State University.
