Abstract:
An integrated circuit which enables the implementation of a high-performance dual-conversion superheterodyne receiver with low power consumption will be described.

The heart of the IC is a bandpass delta-sigma converter which combines LC, active-RC and switched-capacitor resonators to achieve a large dynamic range while consuming only a small amount of power. Reasons for these and other architectural choices will be described while a few "tales from the trenches" provide added entertainment.
Biography:
RICHARD SCHREIER received the B.A.Sc., M.S. and Ph.D degrees from the University of Toronto in 1983, 1985 and 1991, respectively. From 1985 to 1987 he worked for Bell-Northern Research in Ottawa, Canada, and from 1991 to 1997 he was an Assistant/Associate Professor at Oregon State University in Corvallis, Oregon. Since 1997, he has been working for Analog Devices, Inc. in Wilmington Massachusetts. Dr. Schreier is the author of the freeware Delta-Sigma Toolbox for MATLAB and is co-editor (with S.R. Norsworthy and G.C. Temes) of an IEEE Press book on delta-sigma modulation.
