Abstract
A method and apparatus for operating an analog-digital converter for converting an input signal into a multibit output in one conversion cycle. The method includes loading a capacitor array by applying a given input signal potential, evaluating a sampling potential provided by the capacitor array in a number of consecutive decision steps performed by at least two decision latches and changing the sampling potential by switching the capacitor array for each decision step based on a result of the step of evaluating the sampling potential, where the step of evaluating at least one of the decision latches performs the evaluating for two decision steps.
