Abstract

Se describen las modalidades de un aparato para el acoplamiento directo de un sensor capacitivo con un convertidor delta-sigma. Un aparato incluye un sensor, un circuito de acoplamiento de carga configurado para transferir al menos una porción de la carga generada por el sensor a un circuito integrador, un primer circuito de retroalimentación de carga configurado para retroalimentar la carga al sensor, un segundo circuito de retroalimentación de carga configurado para retroalimentar la carga al circuito integrador, un circuito de comparación configurado para detectar la carga acumulada en el circuito integrador para un ciclo actual y para determinar la polaridad de la retroalimentación de carga para un ciclo subsiguiente y un circuito lógico configurado para proporcionar una salida digital que corresponde con la cantidad detectada y también configurado para proporcionar la polaridad de la retroalimentación de carga determinada por el circuito de comparación al primer circuito de retroalimentación de carga y también al segundo circuito de retroalimentación de carga.
