Abstract

Dans un circuit plieur d'un convertisseur analogique-numérique on utilise, pour diminuer la déformation, une chaîne d'émetteurs de transistors alimentée par des sources de courant continu qui sont reliées entre elles par des éléments de seuil. La chaîne est commandée par une source de courant qui fournit le signal d'entrée Application : conversion de signaux analogiques en signaux numériques.
