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.
