Title: Efficient High Performance Spectrum Analysis: Demands, Challenges and Opportunities
Speaker: Degang Chen, Professor of Electrical Engineering, Iowa State University
Abstract: After several decades of innovation in semiconductor technology, electronic circuits and systems today provide orders of magnitude better performance in terms of accuracy, speed, functionality, and cost. In particular, certain circuits, systems, and applications have pushed the resolution and bandwidth envelope to an extent that spectrum evaluation has become highly challenging or impossible with existing methodologies. Example circuits and applications will be described to high light the various fundamental challenges involved in achieving high performance spectrum analysis. Some recent developments will be reviewed. New spectrum analysis algorithms targeted at overcoming part of these challenges will be described. Comparative studies and experimental results will be presented.
Speaker Bio: Degang Chen received his B.S. degree in instrumentation and automation from Tsinghua University in 1984 and his M.S. and Ph.D. degrees in electrical and computer engineering from UC Santa Barbara, in 1988 and 1992, respectively. He was the John R. Pierce Instructor of Electrical Engineering at CalTech before he joined Iowa State University in 1992 where he is currently a Professor of Electrical Engineering. His recent industry experience includes summers with the Boeing Company, Maxim Integrated Products, and Texas Instruments Inc. His current research interests include analog and mixed-signal integrated circuit design and testing, with an emphasis on low-cost high-accuracy testing, built-in-self-test and test-based self-calibration, and on integrated sensor design including temperature sensors and impedance sensors. Dr. Chen received a Best Transaction Paper Award, several best paper awards at international conferences, an SRC Technology Invention Award, a Warrant Boast Outstanding Teaching Award, and an A. D. Welliver Faculty Fellowship.
