How many inverters does it take to make an oscillator? How many inverters does it take to make an amplifier? There is a recent circuit technique that is a little different/strange. Looks like an oscillator, walks like an oscillator, and talks like an oscillator. But it's not an oscillator. It's an amplifier. A first publication at 2012 ISSCC demonstrated what the ring amplifier is capable of, but there is more, and lots of design space to explore. If you've seen it already, you can expect to learn something more about it, perhaps a more insightful/in-depth look at this. If you have never seen the ring amplifier, I hope you'll be pleasantly surprised. Through this seminar, I hope to inform those who attend this talk not only to enjoy learning something new but also to consider for future a very different and hopefully promising way of implementing efficient and high accuracy switched-capacitor circuits.
Un-Ku Moon received his B.S. degree from the University of Washington, Seattle, in 1987, M.Eng. degree from Cornell University, Ithaca, NY, in 1989, and 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. His technical contributions have been in the area of analog and mixed-signal circuits including high linearity filters, timing recovery, PLLs, data converters, and low voltage circuits for CMOS.
He served as the Editor-in-Chief of the IEEE Journal of Solid-State Circuits and the IEEE Transactions on Circuits and Systems II, as a Distinguished Lecturer of the IEEE Solid-State Circuits Society, as an Associate Editor of the IEEE Journal of Solid-State Circuits and the IEEE Transactions on Circuits and Systems II, and as the Deputy Editor-in-Chief of the IEEE Transactions on Circuits and Systems II. He served on governing boards of both the IEEE Solid-State Circuits Society (SSCS AdCom) and the IEEE Circuits and Systems Society (CASS BoG) as the SSCS representative to CASS. He also served as a Technical Program Committee member of the IEEE International Solid-State Circuits Conference, the IEEE VLSI Circuits Symposium, and the IEEE Custom Integrated Circuits Conference. He currently serves on the Executive Committee of the IEEE Symposia on VLSI Technology and Circuits.
