Topic:

Designing Sigma-Delta Data Converters: From Theory Foundations to Chip Implementation

Data converters are key enablers for the feasible implementation of future cyber-physical systems connected in the so-called Internet-of-Things (IoT), where the analog/digital (A/D) interface constitutes in the majority of cases the main design bottleneck. Compared with other data converter architectures – such as SAR or Pipeline – ΣΔ ADCs cover one of the widest resolution-vs-speed conversion regions, being the most efficient solution to digitize diverse types of signals in many diverse applications – from ultra-low-power biomedical devices to ultra-wide-band communications. This versatility, together with their robustness to inaccurate analog integrated components, are some of the reasons why many engineers nowadays, in both industry and academia, consider ΣΔMs as their first choice for their designs. This tutorial presents a systematic and practical design guide of high-performance ΣΔMs – going from specifications and system-level concepts to silicon integration, prototyping and experimental characterization. A number of demonstration vehicles, case studies, and test benches are given to illustrate practical issues and design trade-offs, covering the whole design flow of ΣΔMs – from initial theory and behavioral modeling, to transistor-level and layout design, chip implementation, and experimental measurements. The tutorial contents are structured by following a step-by-step approach, where attendees can learn many design tricks and recipes that can be applied to their own projects.

Biography:

José M. de la Rosa received the M.S. degree in Physics in 1993 and the Ph.D. degree in Microelectronics in 2000, both from the University of Seville, Spain. Since 1993 he has been working at the Institute of Microelectronics of Seville (IMSE), which is its turn part of the Spanish Microelectronics Center (CNM) of the Spanish Council of Scientific Research (CSIC). He is also a Full Professor at the Dept. of Electronics and Electromagnetism of the University of Seville.   

 

His main research interests are in the field of analog and mixed-signal integrated circuits, especially high-performance data converters, including analysis, behavioral modeling, design and design automation of such circuits. In these topics, Dr. de la Rosa has participated in a number of Spanish and European research and industrial projects, and has co-authored some 200 international publications, including journal and conference papers, book chapters and the books Systematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips (Kluwer, 2002), CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error Analysis and Practical Design (Springer, 2006), Nanometer CMOS Sigma-Delta Modulators for Software Defined Radio (Springer, 2011) and CMOS Sigma-Delta Converters: Practical Design Guide (Wiley-IEEE Press, 2013).

 

Dr. de la Rosa is an IEEE Senior Member, Member of the Executive Committee of the IEEE-Spain Section, and a member of the Analog Signal Processing Technical Committee of the IEEE Circuits and Systems Society, where he serves as Chair of the Spanish Chapter. He is currently the Deputy Editor in Chief of IEEE Transactions on Circuits and Systems II: Express Briefs and he served as Associate Editor for IEEE Transactions on Circuits and Systems I: Regular Papers, where he received the 2012-2013 Best Associate Editor Award and served as Guest Editor of the Special Issue on the Custom Integrated Circuits Conference (CICC) in 2013 and 2014. He served also as Guest Editor of the Special Issue of the IEEE J. on Emerging and Selected Topics in Circuits and Systems on Next-Generation Delta-Sigma Converters. He is a member of the Steering Committee of IEEE MWSCAS and he has also involved in the organizing and technical committees of diverse international conferences, among others IEEE ISCAS, IEEE MWSCAS, IEEE ICECS, IEEE LASCAS, IFIP/IEEE VLSI-SoC and DATE. He served as TPC chair of IEEE MWSCAS 2012, IEEE ICECS 2012 and IEEE LASCAS 2015. He is a Distinguished Lecturer of the IEEE Circuits and Systems Society (term 2017-2018).
