I received a Ph.D. in electrical engineering from the University of Illinois at Urbana-Champaign under Prof. Bang-Sup Song. I did my master's degree at Cornell University (Ithaca, NY), and bachelor's degree at Univerisity of Washington (Seattle). I have returned to the Northwest since January 1998 as I joined the Oregon State University (Corvallis). Between the completion of my Ph.D. and coming to OSU, I worked at Bell Labs for four years and designed MOS telecommunication circuits. My past work includes highly linear and tunable continuous-time filters (Ph.D. work), telecommunication circuits including timing recovery and analog-to-digital converters (a bit of Ph.D. work), frequency synthesizers, and switched-capacitor circuits. My current research interests include high-frequency switched-capacitor filters, low-voltage switched-capacitor circuits, high-resolution and oversampling data converters, and highly linear continuous-time filters.
