Incremental Delta-Sigma A/D Converters Analog-to-digital converters are often used in such instrumentation and measurement applications as weight scales, humidity or temperature or pressure sensors. These ADCs usually do not need high speed, but require very high absolute accuracy and linearity, as well as very low offset and noise. Low power is also often an important design consideration. Ordinary delta-sigma ADCs are not well suited for such applications; however, a modified version, the incremental data converter, performs very well. In this seminar, the operating principles of incremental ADCs will be explained, and a recently fabricated 22-bit ADC with 0.3 ppm noise, 2 uV offset, 2 ppm gain error, and 4 ppm INL will be briefly described. Biography: Gabor Temes received his undergraduate education in Hungary. He received his Ph.D. at the University of Ottawa in 1961. He is now a Professor in the School of Electrical Engineering and Computer Science at Oregon State University, and a Professor Emeritus of UCLA. He held positions at UCLA, Ampex Corp., Stanford University and BNR. He is a Life Fellow of IEEE. He received the Technical Achievement Award and the Education Award of the IEEE CAS Society, as well as the IEEE Centennial Medal. He is the recipient of the 1998 IEEE Graduate Teaching Award and received the IEEE Millennium Medal and the IEEE-CAS Golden Jubilee Medal in 2000. He was the recipient of the 2006 IEEE Gustav Robert Kirchhoff Award. Prof. Temes has written many books and papers on discrete and integrated circuit design. _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
