BIOGRAPHY

Bram Nauta was born in Hengelo, The Netherlands in 1964. In 1987 he received the M.Sc degree (cum laude) in electrical engineering from the University of Twente, Enschede, The Netherlands. In 1991 he received the Ph.D. degree from the same university on the subject of analog CMOS filters for very high frequencies. In 1991 he joined the Mixed-Signal Circuits and Systems Department of Philips Research, Eindhoven the Netherlands, where he worked on high speed AD converters and analog key modules. In 1998 he returned to the University of Twente, as full professor heading the IC Design group, which is part of the CTIT Research Institute. His current research interest is high-speed analog CMOS circuits. Besides, he is also part-time consultant in industry and in 2001 he co-founded Chip Design Works.
His Ph.D. thesis was published as a book: Analog CMOS Filters for Very High Frequencies,(Springer, 1993) and he received the "Shell Study Tour Award" for his Ph.D. Work. From 1997 until1999 he served as Associate Editor of IEEE Transactions on Circuits and Systems -II; Analog and Digital Signal Processing. After this, he served as Guest Editor, Associate Editor (2001-2006) - and from 2007 as the Editor-in-Chief for the IEEE Journal of Solid-State Circuits. He is also member of the technical program committees of the International Solid State Circuits Conference (ISSCC), the European Solid State Circuit Conference (ESSCIRC), and the Symposium on VLSI circuits. He is co-recipient of the ISSCC 2002 and 2010 "Van Vessem Outstanding Paper Award", is distinguished lecturer of the IEEE, elected member of IEEE-SSCS AdCom and IEEE fellow.

BIOGRAPHY

Markus Helfenstein was born in Lucerne, Switzerland, in 1962. He received the Bachelor degree from the Inst. of Technology in Lucerne in 1986, the diploma and the Dr. Sc. Techn. degree in electrical engineering from the Swiss Federal Institute of Technology in 1992 and 1997. He also received an MBA in telecommunications management from the University of Fribourg, Switzerland, in 2007.
From 1986 to 1988 he was a Research Engineer at Mettler Instrumente AG, Switzerland, involved in the design of high resolution counter IC chips. In 1998, he co-founded Anadec GmbH, a start-up company which holds patents on the design of analog VLSI iterative decoders. Between 2000 and 2002 he was with Globespan Inc. (now Conexant) involved in projects on the design of mixed-signal chips for xDSL applications.

BIOGRAPHY

Diego Vázquez received the Licenciado (BS) degree in Physical Sciences from the University of Seville (Spain) in 1989, and his PhD degree from the same university on the subject of design and test of analog and mixed-signal integrated circuits in 1995.
Since 1990, he is with the Department of Electronics and Electromagnetism at the University of Seville, where he is currently a professor, and with the National Microelectronic Center (today IMSE-CNM), where he carries out his main research activities.
His research interests include design, test and design-for-test techniques for RF, analog and mixed-signal circuits and systems. He has several patents and has published a large number of articles in these fields. Among them, analog filters (including continuous-time and switched-capacitor) have been one of the sub-topics where more attention has been paid to.
