A 25 Ms/s Nyquist-Rate Sigma-Delta Modulator for a Wideband CDMA Receiver

David A. Sobel, 2000, M.S. (advisor: Bob Brodersen)

The Primary goal of this research is to design a very high-speed, low-power sigma-delta ADC for a highly-integrated, CMOS directed-conversion receiver front-end of a wideband CDMA wireless link.  A secondary goal is to further understand the area of system and circuit co-design, so that the interactions between the analog circuits of the sigma-delta modulator and the back-end algorithms can be understood and exploited.
