Abstract: Embodiments of the present invention generally provide a processing system for an input device including a sensor module having sensor circuitry. The sensor module may be coupled to transmitter electrodes, receiver electrodes, and a shield electrode. The sensor module may be configured for transmitting transmitter signals with the transmitter electrodes, receiving resulting signals with the receiver electrodes, and transitioning the shield electrode from a first voltage to a second voltage during a non-sensing time period. The resulting signals may include effects which correspond to the transmitter signals. The input device may further include a determination module configured for determining positional information for an input object based at least in part on the resulting signals.
