Abstract

Selon l'invention, la phase d'un signal de sortie est fondée sur une comparaison entre un signal oscillant et un seuil réglable. Le réglage du seuil entraîne un réglage correspondant de la phase du signal de sortie. Par exemple, le seuil réglable peut comprendre un signal de polarisation réglable d'un circuit de transistor, le signal oscillant étant fourni sous la forme d'une entrée du circuit de transistor et la sortie du circuit de transistor constituant le signal de sortie. Dans certains aspects, on peut utiliser les procédés de réglage de phase de l'invention pour produire une ou plusieurs horloges multiphases accordables.
