Conference Paper

An IC Chip Set for 20 Bit A/D Conversion

Authors: Adams, Robert W.

AES Conference: 7th International Conference: Audio in Digital Times · Paper 7-011 · May 1989

Abstract

A chip set has been developed which implements a high-resolution A/D converter using the noise-shaping/digital decimation technique presented in an earlier paper. The chip set consists of a front-end IC to implement the noise-shaping algorithm and a digital decimator IC to reduce the sampling rate. A new method of canceling the effects of digital waveform asymmetry has been developed, resulting in increased resolution. The application circuit in its minimum configuration gives a dynamic range of 108 dB. More complex configurations yield a dynamic range of 114 dB.
