BIOGRAPHY
|
Christian C. Enz (M’84) received the M.S. and Ph.D. degrees in electrical engineering from the Swiss Federal Institute of Technology, Lausanne (EPFL) in 1984 and 1989 respectively.
From 1984 to 1989 he was research assistant at the EPFL, working in the field of micropower analog CMOS integrated circuits (IC) design. In 1989 he was one of the founders of Smart Silicon Systems S.A. (S3), where he developed several low-noise and low-power ICs, mainly for high energy physics applications. From 1992 to 1997, he was an Assistant Professor at EPFL, working in the field of low-power analog CMOS and BiCMOS IC design and device modeling. From 1997 to 1999, he was Principal Senior Engineer at Conexant (formerly Rockwell Semiconductor Systems), Newport Beach, CA, where he was responsible for the modeling and characterization of MOS transistors for the design of RF CMOS circuits. In 1999, he joined the Swiss Center for Electronics and Microtechnology (CSEM) where he launched and lead the RF and Analog IC design group. In 2000, he was promoted Vice President, heading the Microelectronics Department.
He is also lecturing and supervising undergraduate and graduate students in the field of analog and RF IC design at EPFL, where he is Professor since 1999. His technical interests and expertise are in the field of very low-power analog and RF IC design and semiconductor device modeling, with a particular focus on noise. He is the author and co-author of more than 140 scientific papers and has contributed to numerous conference presentations and advanced engineering courses.
Together with E. Vittoz and F. Krummenacher he is one of the developer of the EKV MOS transistor model and the author of the book "Charge-Based MOS Transistor Modeling - The EKV Model for Low-Power and RF IC Design" (Wiley, 2006).
He is member of several technical program committees, including International Solid-State Circuits Conference (ISSCC) and European Solid-State Circuits Conference (ESSCIRC). He has served as a vice-chair for the 2000 International Symposium on Low Power Electronics and Design (ISLPED), exhibit chair for the 2000 International Symposium on Circuits and Systems (ISCAS) and is chair of the technical program committee for the 2006 European Solid-State Circuits Conference (ESSCIRC).
Since 1989, he is a member of IEEE and President of the IEEE Solid-State Chapter of West Switzerland.
