Abstract
An input device associated with a sensing region is provided. The input device includes: a sensor electrode configured to receive a resulting signal associated with the sensing region; an auxiliary component configured to generate an output based on a differential current; a mixer circuit coupled to the sensor electrode and including: a current conveyor configured to generate a replica of the resulting signal; and a switch array, in series with the replica and the differential current, and configured to generate the differential current by demodulating the replica of the resulting signal.
