A circuit device has a passive network () with an input () and an output, the output of the passive network () forming an output terminal () of the circuit device and a feedback path coupling the output terminal () of the circuit device to the input () of the passive network (), the feedback path having an amplifier () configured to adjust an attenuation of the circuit device.

Circuit device for filtering or impedance matching

A DC-offset correction circuit includes an analog circuit to generate a plurality of analog offset-correction signal values, each of which are assigned to a hop band. The analog circuit is coupled to a tap of an analog receiver chain and includes a first analog selector to select an analog offset-correction signal value, the selected analog offset correcting signal value being assigned to a current hop band. Further, the DC-offset correction circuit includes a combiner to combine a received signal with the selected analog offset-correction signal value and feed the analog receiver chain.
