Robustness and Resiliency in Data Conversion

November 12, 2010
Time: 2:00pm-12:00pm
414 CEPSR/Schapiro Building
Speaker: Dr. Yun Chiu (University of Texas at Dallas)


As the performance and cost-per-function continue to excel for microelectronic devices, the underlying economic driving force is rapidly adapting the fabrication technology to meet the critical needs of the industry. Our past research has shown that with the leverage of system-level and digital techniques, energy efficiency can be continually accelerated for data conversion circuits in scaled technology nodes. While the approach is making significant progresses in marching the benchmark of CMOS ADC figure-of-merit (FoM), a paradigm-shifting challenge has emerged in the nano-scale regime and beyond: analog robustness and resiliency, in the headwind of exponentially growing process/device variability and degrading operation environment due to mixed-signal integration. In this talk, I will identify a few architectural and circuit techniques to cope with the new challenges in the data conversion area. The focus will be placed on redundant analog architectures and judicious application of digital techniques for error correction. Some prototype results will be showcased during the talk.


Yun Chiu received his Ph.D. degree in electrical engineering and computer sciences from the University of California at Berkeley. He worked as a Senior Staff Member at a start-up company in Fremont, California developing CMOS digital imaging products from 1997 to 1999. Dr. Chiu was an assistant professor in the ECE Department of the University of Illinois at Urbana-Champaign from 2005 to 2010. He is now with the Texas Analog Center of Excellence (TxACE) of the University of Texas at Dallas, where he is an associate professor of the EE Department and holds the TxACE Endowed Professorship of Electrical Engineering. Dr. Chiu received the Jack Kilby Award from the 2005 International Solid-State Circuits Conference, the 2009 ISSCC/DAC Student Design Contest Award, and the Agilent Foundation Award in 2009. He was an Associate Editor of the IEEE Transactions on Circuits and Systems II: Express Briefs, and has served on the technical program committees of the IEEE Custom Integrated Circuits Conference, Asian Solid-State Circuits Conference, etc. Dr. Chiu is an IEEE senior member and the author of the book Analysis and Design of Pipelined Analog-to-Digital Converters.
