Yannis P. Tsividis is a leader in the development of analog and mixed-signal integrated circuits across a variety of platforms. 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 significant contributions to the field, ranging from precision device modeling and novel circuit building blocks to new techniques for analog and mixed-signal processing, self-correcting chips, switched-capacitor circuit theory, RF integrated circuits, and mixed analog-digital VLSI computation. This foundational research has resulted in several patents in several countries. A fellow of the IEEE, he is the recipient of the IEEE Undergraduate Teaching Award and the IEEE Gustav Robert Kirchhoff Award. The 2014 fall issue of IEEE Solid-State Circuits Magazine was devoted to Professor Tsividis and his unique contributions to the discipline of solid-state circuits; it was entitled Yannis Tsividis: Path-Breaking Research and Educator.
The Edwin Howard Armstrong Professorship in the Faculty of Engineering and Applied Science was established by the University Trustees in 1979 to support a talented teacher and researcher at Columbia Engineering. Endowed by a transfer from the Percy K. and Vida L.W. Hudson Fund and a gift from Mrs. Marion Armstrong, the professorship honors noted alumnus (Class of 1913) and faculty member Edwin Howard Armstrong (1890-1954), who designed wide-band frequency modulation (FM) radio and invented three electronic circuits fundamental to modern radio, television, and radar. The Edwin Howard Armstrong Professor may hold an appointment in any of the departments of the School.
