Abstract:
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 ( 200 ) from generating an interference signal that can cause a signal distortion at the output of a current-to-voltage converter ( 300 ) 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 ( 200 ) or the current at the second output of the frequency divider ( 200 ) 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.

Claim (Index 1):
A filter circuit to suppress a signal distortion, comprising a current-to-voltage converter, a frequency divider and a compensation circuit arrangement, whereby the frequency divider has at least one input, a first output and a second output, whereby the input of the frequency divider has a first impedance in a first frequency band and a second impedance in a second frequency band, and the second frequency band has higher frequencies than the first frequency band, whereby the first output has a third impedance in the first frequency band and a fourth impedance in the second frequency band, and the absolute value of the fourth impedance is greater than or equal to the absolute value of the third impedance, whereby the second output has a fifth impedance in the first frequency band and a sixth impedance in the second frequency band, and the absolute value of the fifth impedance is greater than or equal to the absolute value of the sixth impedance, whereby an input of the current-to-voltage converter is connected to the second output of the frequency divider, whereby the compensation circuit arrangement is configured to detect a first signal current between the input and the first output of the frequency divider, whereby the signal current generates a distortion current between the input of the current-to-voltage converter and the second output of the frequency divider, and whereby the compensation circuit arrangement is configured to compensate for the distortion current in such a way that a distortion-free output signal is made available.
