A circuit configuration for calibrating the switching points of a decision module that is controlled by an analog input signal, in dependence on a direct component contained in the input signal in addition to an alternating component, is described. The circuit configuration contains a peak detector for detecting the upper and lower signal peaks of the input signal, a controllable reference unit for providing a reference value, an arithmetic unit for determining a mean value, and a comparison unit. In addition, the circuit configuration has a control unit for compensating the direct component of the input signal and a second control unit which is connected downstream of the comparison unit on the input side and is connected to the reference unit on the outputs side for inversely correcting the reference value.
