Abstract
A circuit configuration for offset compensation includes a filter device for ascertaining a direct component in an input signal delivered to it and a linking device for subtractive linking of the input signal and an output signal of the filter device. A tracking and holding device which is connected between the filter device and the linking device is controllable by a control signal. The control signal is furnished by a window comparator device having an input to which the input signal is applied. When the input signal is within a predetermined window, the tracking and holding device is located in a tracking mode, while otherwise it is in a holding mode.
