Abstract:
An asynchronous capacitance-to-digital converter (CDC) is described that allows for very low-power operation when during inactive periods (when no conductive object is in contact or proximity to the sensing electrodes). Asynchronous operation of the CDC provides for capacitance-to-digital conversion without the use of system resources and more power intensive circuit elements.

Claim (Index 8):
A capacitance-to-digital converter (CDC) comprising:\n a comparator having a first input coupled to a first sensing electrode and a second input coupled to a second sensing electrode; a first capacitive digital-to-analog converter (DAC) coupled to the first input of the comparator, the capacitive DAC for applying a first signal to the first sensing electrode; a second capacitive digital-to-analog converter (DAC) coupled to the second input of the comparator, the capacitive DAC for applying a second signal to the second sensing electrode; and a counter for providing control signals to the first and second capacitive DACs, the counter receiving logic signals from a logic unit coupled to an output of the comparator, wherein a capacitance change is detected by a processing unit when a first value of the counter is substantially different from a second value of the counter.
