Abstract

L'invention concerne un convertisseur analogique-numérique conçu pour détecter des signaux de détection pouvant comprendre un filtre à boucle et un convertisseur numérique-analogique à rétroaction. Le filtre à boucle peut comprendre une entrée de filtre à boucle conçue pour recevoir un signal d'entrée courant d'un capteur et pour générer un signal de sortie en réponse au signal d'entrée courant. Le convertisseur numérique-analogique peut comprendre une sortie de rétroaction conçue pour générer un signal de sortie de rétroaction en mode courant ou en mode charge en réponse au signal de sortie, la sortie de rétroaction étant couplée à l'entrée du filtre à boucle afin de combiner le signal courant d'entrée et le signal de sortie de rétroaction à l'entrée.
