Abstract
Pour qu'un générateur de phase réponde à deux modes d'activation selon que l'une ou l'autre de deux tensions d'entrée est en avance ou en retard sur l'autre en leurs transitions d'un sens déterminé d'un premier niveau de tension à un second niveau. Le circuit incorpore un montage d'entrée ne se débloquant pour activer un montage de sortie à deux niveaux de tension que lorsqu'une transition de sens défini dans l'une des tensions s'effectue après qu'une transition de sens défini se soit produite dans l'autre des tensions, l'ordre de ces transitions étant indifférent au résultat requis. Ce déblocage assure un trajet de décharge d'un noeud de potentiel pré-chargé et relié par un suiveur-adaptateur de niveaux à une entrée d'activation du montage de sortie. Applications : générateurs de phase de commande d'opérations dans les systemes informatiques.
