Zusammenfassung:A process includes receiving an associated input signal via a receiver electrode of a sensor array, the associated input signal indicative of an associated mutual capacitance of the receiver electrode; adding a balancing signal to the associated input signal to generate a balanced input signal at least partially responsive to a number of sensor nodes at the receiver electrode; generating a voltage signal indicative of the associated mutual capacitance of the receiver electrode at least partially responsive to a balanced input signal; and generating a digital value representative of the voltage signal.
