in the design of analog and RF circuits. Alberto Sangiovanni-Vincentelli Contributing Authors Piet Vanassche received the MSc and PhD degrees in Electrical Engineering from the Katholieke Universiteit Leuven in 1997 and 2003 respectively. His Ph.D. research dealt with techniques for high-level exploration and trade-off analysis for mixed signal telecommunication systems. For this work he obtained a fellowship from the Institute for Science and Technology (IWT). His research interests are in simulation and syn- thesis of telecommunication systems, network analysis, control theory and engineering education. Currently, he is working for Siemens on advanced process control. He is a member of IEEE. Georges Gielen received the MSc and PhD degrees in Electrical Engineering from the Katholieke Universiteit Leuven in 1986 and 1990 respectively. He is now a full-time professor at the Katholieke Universiteit Leuven. His research interests are in the design of analog and mixed-signal integrated circuits, and especially in analog and mixed- signal CAD tools and design automation (modeling, simulation and symbolic analysis, analog synthesis, analog layout generation, analog and mixed-signal testing). He has authored or coauthored two books and more than 160 papers in edited books, interna- tional journals and conference proceedings. He regularly is a member of the Program Committees of international conferences (ICCAD, DAC, DATE, ...), he is a Deputy Editor of the IEEE Transactions on Circuits and Systems, part II, and is a member of the Editorial Board of the Kluwer international journal on Analog Integrated Circuits and Signal Processing. He is a member of the Board of Governors of the IEEE Circuits and Systems (CAS) Society, and is the Chairman of the IEEE Benelux CAS Chapter. He was the 1997 Laureate of the Belgian Royal Academy of Sciences, Literature and Arts, in the category of engineering sciences. He also received the 1995 Best Paper award of the John Wiley international journal on Circuit Theory and Applications. He
