Abstract

a. Circuit oscillant comprenant un oscillateur ayant une première borne de sortie créant un premier signal de référence. b. Circuit caractérisé en ce qu'il comporte un convertisseur transformant une tension en une intensité, ce convertisseur ayant une borne d'entrée de faible impédance et une borne de sortie constituant la seconde borne de sortie du circuit pour créer un second signal de référence ainsi qu'un condensateur branché entre la première borne de sortie et la borne d'entrée du convertisseur, le premier et le second signal de référence étant ainsi déphasés de 90 degrés l'un par rapport à l'autre.
