Title (EN) NANO-POWER CAPACITANCE-TO-DIGITAL CONVERTER
(FR) CONVERTISSEUR CAPACITIF-NUMÉRIQUE À NANO-PUISSANCE
Abstract:
(EN) 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.
(FR) L'invention concerne un convertisseur capacitif-numérique (CDC) asynchrone qui permet un fonctionnement à très faible puissance lors de périodes inactives (lorsqu'aucun objet conducteur n'est en contact avec les électrodes de détection ou à proximité de celles-ci). Le fonctionnement asynchrone du CDC permet une conversion capacitif-numérique sans faire appel à des ressources système ni à des éléments de circuit à plus forte intensité de puissance.
