Abstract
In certain embodiments, an apparatus comprises a charge-measurement capacitor and circuitry. The circuitry is configured to provide a pre-determined amount of charge to the charge-measurement capacitor and transfer an accumulated amount of charge on a sense electrode to the charge-measurement capacitor, the accumulated amount of charge having accumulated on the sense electrode due at least in part to noise. The circuitry is configured measure a voltage of the charge-measurement capacitor to determine the accumulated amount of charge.
