Efficient High Resolution Incremental ADCs
High-resolution, high-efficiency converters are dominated by noise-shaping and oversampling architectures. However, in applications where true Nyquist-rate conversion is required, such as single-shot conversion, multiplexing, or time-interleaving, neither oversampling nor noise-shaping can be used. This is due to the very concepts that allow them to combine efficiency with performance, introduce memory into the system, and thus prevent sample-to-sample operation. This talk presents approaches to get around this, i.e. to combine Nyquist rate conversion with high power efficiency through innovative architecture and circuit design with a focus on incremental delta-sigma ADCs.

Maurits Ortmanns of Ulm University
Efficient High Resolution Incremental ADCs
Biography:
Maurits Ortmanns (Senior Member, IEEE) received the degree of Dr.-Ing. from the University of Freiburg, Germany, in 2004. From 2004 to 2005, he worked at Sci-Worx GmbH, Hannover, Germany, in the area of mixed-signal circuits for biomedical implants. In 2006, he joined the University of Freiburg as an assistant professor. Since 2008, he is a full professor at the University of Ulm, Germany, where he is the director of the Institute of Microelectronics. He is the author of the textbook Continuous-Time Sigma-Delta A/D Conversion, author or co-author of several other book chapters, and over 350 IEEE journal articles and conference papers. He holds many patents. He has served as a program committee member of ISSCC, ESSCIRC, DATE, and ECCTD, as ISSCC EU regional chair, and ISSCC analog subcommittee chair. He has served as an Associate Editor for TCAS, Guest Editor for JSSC, and as a Distinguished Lecturer for SSCS. His research interests include mixed-signal integrated circuit design with special emphasis on data converters and biomedical applications.
