Abstract
A method, apparatus, and system are described to perform, by a capacitance-sensing circuit, capacitance sensing of an electrode of a capacitive sense array of electrodes. Performing the capacitance sensing includes integrating, on a passive integrator circuit, charge from a sensed capacitance of the electrode of the capacitive sense array. The passive integrator circuit integrates the charge on a self-capacitance of the electrode as part of the integrating. The capacitance-sensing circuit converts the charge from the sensed capacitance of the electrode into a digital value representing the sensed capacitance of the electrode.
