Abstract
In one embodiment, a method includes substantially simultaneously applying a pre-determined voltage to a sense electrode and a corresponding drive electrode of a touch sensor. The application of the pre-determined voltage providing a measurement current at a capacitance including the sense electrode. The method also includes determining a difference between the measurement current at the capacitance and a reference value; and determining whether a proximity input to the touch sensor has occurred based at least in part on the difference.
