description A low-pass filter (300) comprising: a filter input terminal (302); a filter output terminal (304); a filter FET (306) configured to provide a resistance between the filter input terminal (302) and the filter output terminal (304); a filter capacitor (308) connected between the filter output terminal (304) and a reference terminal; a bias FET (310) configured to provide a bias voltage to the filter FET (306); a buffer (316) connected between the filter input terminal (302) and the bias FET (310), the buffer (316) configured to source a bias current for the bias FET (310); and an offset voltage source (220; 220'; 320) configured to contribute to the bias voltage provided to the filter FET (306).
