Yannis P. Tsividis is Charles Batchelor Professor of Electrical Engineering. Starting with the first fully integrated MOS operational amplifier, which he demonstrated in 1976, he has done extensive work in analog and mixed-signal integrated circuits at the device, circuit, system, and computer simulation level. He and his students have been responsible for several contributions, ranging from precision device modeling and novel circuit building blocks to new techniques for analog and mixed-signal processing, self-correcting chips, switched-capacitor network theory, RF integrated circuits, mixed analog-digital VLSI computation and the creation of computer simulation programs. This work has resulted in several patents in several countries. He is the recipient of the 1984 IEEE W. R. G. Baker Best Paper Award, the 1986 European Solid-State Circuits Conference Best Paper Award, and the 1998 IEEE Circuits and Systems Society Guillemin-Caure Best Paper Award. He is corecipient of the 1987 IEEE Circuits and Systems Society Darlington Best Paper Award and the 2003 IEEE International Solid-State Circuits Conference L. Winner Outstanding Paper Award. He is a fellow of the IEEE, and received a Golden Jubilee Medal from the IEEE Circuits and Systems Society in 2000. At Columbia, he has received the 1991 Great Teacher Award from the Alumni Association, the 1998 Distinguished Faculty Teaching Award from the Engineering School Alumni Association, and the 2003 Presidential Award for Outstanding Teaching. In 2005, he received the IEEE Undergraduate Teaching Award.
