Calibration method for redundant AD or DA converters with weighted arrays

摘要

The method according to the invention relates to a self-calibration of redundant A/D and D/A convertors with weighted array and error correction, which is based on the fact that the weighting of the individual elements (C0 to Cn) is calculated with respect to the sum (FS) of all weighted elements so that the digital code can be manipulated with the aid of error correction methods in order to achieve a correct conversion with high resolution and high conversion speed and, at the same time, low requirements for the accuracy of individual weighted elements.
