Abstract
An apparatus having a processing device for calibrating a touch-sensor device with calibration capacitors is described. Methods of calibrating the touch-sensor device using the same are also described. Processing device and multiple calibration capacitors are disposed on an integrated circuit (IC) die substrate. The processing device includes a measurement circuit to be coupled to a touch-sensor device and a switching circuit to selectively couple the calibration capacitors to the measurement circuit. The processing device is configured to calibrate the touch-sensor device by applying one or more capacitance touch values from one or more of the calibration capacitors using the switching circuit. The one or more capacitance touch values simulate a touch on the touch-sensor device.
