Biography

Sayfe Kiaei is a professor in the School of Electrical, Energy and Computer Engineering, the director of the Connection One Center (National Science Foundation (NSF) I/UCRC Center), and Motorola Chair in Analog and RF Integrated Circuits. From 1993 to 2001, he was a senior member of technical staff with the Wireless Technology Center and Broadband Operations at Motorola. Prior to that, Kiaei was a professor at Oregon State University (1987-1993), where he taught courses and performed research in RF, Analog, VLSI and Communication Systems. Kiaei has established two Industry-University Cooperative Research Centers: Center for the Design of Analog/Digital ICs (CDADIC) where he was a co-director from 1987-1993, and the Connection One Center at Arizona State University. He has published more than 200 journal and conference papers and holds several patents. His research interests are in RF, Analog and Digital IC, Transceiver design and sensors.
