Abstract
A touch panel sensor system configured to measure mutual-capacitance and self-capacitance is disclosed. The touch panel sensor system includes a sensor configured to detect a change in capacitance associated with a touch event upon a touch panel and a measuring component. The measuring component is configured to detect mutual-capacitance during the first mode of operation and to detect self-capacitance during the second mode of operation. The system also includes a selection component that is configured to receive a selection signal to cause selection of the mode of operation. The system also includes a driver component coupled to the selection component and configured to generate a drive signal, which is furnished to the sensor during the first mode of operation and furnished to the measuring module during the second mode of operation. The amplitude characteristic of the drive signal may have differing values for the first and second modes of operation.
