Title
Energy-efficient on-chip power management: System, circuit and device perspectives
Speaker
Dr. Eduard Alarcón, (Professor, Universitat Politecnica De Catalunya)
Abstract
Trends in portable applications such as mobile terminals for next generation communications proceed in the
direction of increasing the computational load while concurrently reducing size and enhancing operating
lifetime. Conversely, the density of energy sources is only expected to slightly increase. In front of this
scenario, there exists a demand in improved power management integrated circuits to avoid a powering crisis
in future systems-on-chip. The ultimate step consequently consists in the fully monolithic integration of the power converter together with the circuits that constitute its load within either the same substrate or chip package, yielding a complete Powered System on a Chip (PSOC). This lecture will cover efficient energy processing circuits within an integrated circuit environment, which requires a multidisciplinary approach through concurrence of analog and mixed-signal IC design, power electronics and control theory disciplines. Topics covered will encompass on-chip power supply design and implementation, efficiency optimization, IC-compatible power inductors and capacitors, power MOSFET switches and efficient switch drivers,
analog current-mode controller IC design, digital controllers, system and circuit-level design of on-chip
adaptive power management techniques, adaptive wideband envelope-tracking power supplies for RF power amplifiers, and adaptive voltage scaling for low-power microprocessor and DSP supply.
Biography
Eduard Alarcón (S'96, M'01) received the M. Sc. (national award) and Ph.D. degrees in electrical engineering from the Technical University of Catalunya (UPC), Barcelona, Spain, in 1995 and 2000, respectively. Since 1995 he has been with the Department of Electronic Engineering at the Technical University of Catalunya, where he became Associate Professor in 2000. During the period 2006-2009 he has been Associate Dean of International Affairs at the School of Electrical Engineering, UPC. From August 2003 to January 2004, he was a Visiting Professor at the CoPEC center, University of Colorado at Boulder, USA. He has co-authored more than 130 international scientific publications, 3 book chapters and 2 patents, and has been
involved in different national and US R&D projects. His current research interests include the areas of analog and mixed-signal integrated circuits, on-chip power management circuits, wireless energy transfer and nanonetworks. He has given 12 invited or plenary lectures and tutorials in Europe, America and Asia, and has been elected by the IEEE CAS society as distinguished lecturer for 2009-2010. He was recipient of the Myril B. Reed Best Paper Award at the 1998 IEEE Midwest Symposium on Circuits and Systems. He
was the invited co-editor of a special issue of the Analog Integrated Circuits and Signal Processing journal devoted to current-mode circuit techniques, and a special issue of the International Journal on Circuit Theory and Applications. He co-organized two special sessions related to on-chip power management at IEEE ISCAS03 (Bangkok, Thailand) and IEEE ISCAS06 (Kobe, Japan) and a tutorial at IEEE ISCAS09 (Taipei, Taiwan). He was the 2007 Chair of the IEEE Circuits and Systems Society Technical Committee
of Power Systems and Power Electronics Circuits. He was the technical program co-chair of the 2007 European Conference on Circuit Theory and Design - ECCTD07 (Seville, Spain), track chair of the IEEE ISCAS 2007 (New Orleans, US), IEEE MWSCAS07 (Montreal, Canada), IEEE ISCAS 2008 (Seattle, US), ECCTD?9 (Antalya, Turkey) and IEEE MWSCAS09 (Cancun, Mexico). He served as an Associate Editor of the IEEE Transactions on Circuits and Systems - II: Express briefs (2006-2007) and currently serves as Associate Editor of the Transactions on Circuits and Systems - I: Regular papers (2006-2009).
