Abstract
In one embodiment, a method includes modifying an amount of charge of a capacitance of a touch sensor resulting in a voltage at the capacitance being a reference voltage level. The method also includes modifying the amount of charge of the capacitance resulting in the voltage at the capacitance being a first pre-determined voltage level. The modified amount of charge of the capacitance induces a first amount of charge on an integration capacitor and the first amount of charge modifies the voltage at the integration capacitor from an integration-reference voltage level to a first charging voltage level. The method also includes modifying the amount of charge of the capacitance resulting in the voltage at the capacitance being a second pre-determined voltage level. The modified amount of charge of the capacitance inducing a second amount of charge on the integration capacitor.
