Abstract
An input device associated with a sensing region is disclosed. The input device includes: a sensor electrode configured to receive a resulting signal associated with the sensing region; a current conveyor configured to generate a first replica of the resulting signal; a mixer circuit configured to generate a differential current by demodulating the first replica of the resulting signal; an interference detection circuit (IDC) configured to: generate a second replica of the resulting signal based on the first replica; determine the second replica includes an interference signal based on a reference current; and generate an interference alert signal in response to determining the second replica includes the interference signal; and an auxiliary component configured to generate an output based on the differential current and the interference alert signal.
