The invention relates to a filter circuit which, on the hardware level, prevents charge transfers caused by one or more currents in a frequency divider () from generating an interference signal that can cause a signal distortion at the output of a current-to-voltage converter () belonging to a filter circuit. This signal distortion would otherwise have to be removed by means of laborious post-processing of the signal. In this process, the voltage curve at the input of the frequency divider () or the current at the second output of the frequency divider () are employed so that, by means of a compensation circuit arrangement, it is possible to model a compensation signal that essentially compensates for an interference signal caused by the charge transfers. The invention also relates to an associated method.
