Abstract
Noise (dither) is introduced into a subranging analog-to-digital converter to enhance conversion accuracy. The resolution of the noise is sufficiently fine that its least significant bits can be changed without always changing the second pass approximation from the converter's internal analog-to-digital converter. Additional bits of statistical resolution can thereby be achieved without sacrificing the overlap between the dither word and the first pass digital approximation that is needed to provide dithered error correction.
