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.

Sensor side charge cancellation

A capacitive sensor is disclosed. The capacitive sensor comprises a plurality of spaced-apart X traces disposed along an X axis and a plurality of spaced-apart Y traces disposed along a Y axis with each of the Y traces forming a single crossing with each of the X traces. The X traces and the Y traces are arranged in an intertwined pattern about each crossing. The X traces and the Y traces are insulated from each other.
