Abstract
In one embodiment, a method includes modifying a voltage at a capacitance of a touch sensor to a first voltage level. The method also includes modifying the voltage at the capacitance to a second voltage level, resulting in a first current. The method also includes modifying a voltage at an integration capacitor to a charging-voltage level based on the first current. The method also includes determining whether a touch input to the touch sensor has occurred based on the charging-voltage level.
