An IF-to-Bits Converter IC
How to Make an ADC with Inductors


A bandpass delta-sigma ADC constructed with inductors offers the means to achieve low noise and high dynamic range with low power. This talk will focus on the architecture and design of such an ADC manufactured by Analog Devices. The ADC achieves 90dB of dynamic range with a 333kHz bandwidth for IFs in the range 30-300MHz, while consuming only 50mW.


Richard Schreier received his PhD in 1991 from the University of Toronto. From 1991 to 1997 he was an Assistant/Associate Professor at Oregon State University. Since 1997 he has been with the High Speed Converters Group of Analog Devices in Wilminton, MA. The talk to be given is based on the work described in his award-winning 2002 ISSCC presentation. Dr. Schreier is the author of the Delta- Sigma Toolbox for MATLAB, and is a co-editor (with G.C. Temes and S. Norsworthy) of an IEEE Press book on Delta-Sigma. A new book, "Understanding Delta-Sigma Data Converters," by Schreier and Temes, is slated to hit the shelves shortly.
