Abstract

La présente invention concerne un procédé et un dispositif de linearisation de la caractéristique exponentielle d'un composant électronique, et notamment de la caractéristique température/résistance d'une thermistance. Selon l'invention la grandeur de sortie du composant est comparée avec une grandeur de sortie d'un circuit de référence variant exponentiellement dans le temps dans le même sens que ladite caractéristique et l'on mesure le temps compris entre un instant initial fixe situé dans la période de variation exponentielle et l'instant auquel les deux grandeurs de sortie sont égales. Application notamment aux instruments de mesure électroniques à affichage numérique.
