New A/D converter architectures based on Gray coding

In this paper, we propose the use of Gray codes in algorithmic and pipeline A/D converters. The major advantage is the tolerance to offset errors in circuit realizations compared with traditional A/D converters using binary coding. Both theoretical investigation and system simulation indicate that the Gray code algorithmic and pipeline AID converters are well suited for high-resolution and/or low-distortion applications.
