Abstract
An analog-digital converter with successive approximation includes a capacitor array for being loaded by applying a given input signal potential and for providing a sampling potential, wherein capacitors of the capacitor array are serially coupled with switches. A decision latch is included for evaluating the sampling potential in a number of consecutive decision steps. The analog-digital converter also includes a logic unit for selectively changing the sampling potential by selectively switching switches associated to the capacitors of the capacitor array for each decision step based on an evaluation result of a previous decision step, wherein the switches are respectively coupled with a calibration switch.
