Dither technique for improving dynamic non-linearity in an analog to digital converter, and an analog to digital converter having improved dynamic non-linearity

摘要

An analog to digital converter comprising a conversion engine having redundancy therein; and a dither device for applying a dither to the conversion engine; and a controller adapted to operate the conversion engine to perform a successive approximation conversion of the analog input, and wherein the dither is removed prior to completion of the analog to digital conversion.
