Jürgen Hertle,
Folding and Interpolating A/D Converters
for Communications Applications

2004; 180 pages. 64,00. ISBN 3-89649-950-5

This dissertation describes the analysis and design of folding and interpolating A/D converters for communications applications in mainstream sub-micron CMOS technologies. A comprehensive discussion of the quantization process is conducted which provides insight into the principle limitations of A/D conversion. Also the speed, noise and accuracy limiting effects of the architecture are presented. The results are used to design two A/D converters. One operates at 50MS/s and achieves a measured SNDR of 42dB. In the second design a calibration structure tailored to folding and interpolating A/D converters is embedded to overcome the limited accuracy capabilities of the architecture.
Jürgen Hertle received the Dipl. Ing. degree in Electrical Engineering from the University Erlangen/Nürnberg in 1997. From 1997 to 1998 he was with the Fraunhofer Institute of Integrated Circuits, Erlangen, Germany. In 1998 he joined the Integrated Systems Laboratory of ETH as a research and teaching assistant, where he worked on the field of analog and mixed-signal integrated circuit design with emphasis on high speed, medium resolution A/D converters.
