Abstract

An input device includes a receiver electrode, a transmitter electrode and a processing system coupled to the receiver electrode and transmitter electrode. The processing system is configured to transmit a transmitter signal with the transmitter electrode during a first time period, inject a charge onto the receiver electrode during a second time period, and receive a resulting signal from the receiver electrode during a third time period. The resulting signal includes effects corresponding to the injected charge. The second time period and the third time period are non-overlapping.
