ABSTRACT:
A method for self-calibration of an analog/digital converter or of a digital/analog converter is performed in a converter including at least one main network with weighted reference elements and one correction network being coupled with the main network for error correction and having weighted further reference elements. The method includes self-calibrating a portion of the reference elements of the main network between two conversions and ascertaining a correction value associated with the portion of the reference elements.
