Abstract

L'invention concerne un circuit comparateur de phase numérique. Il comprend une source de courant 10 susceptible de produire un courant d'une première polarité, un courant d'une deuxième polarité, ou un courant nul selon les signaux qui sont appliqués à ses bornes d'entrée 21 et 22, un premier et un deuxième circuit bistable il et 12, et un premier et un deuxième circuit de formation d'impulsions 14 et 13. Ce comparateur numérique permet de résoudre les difficultés liées à l'existence de retards pour les très faibles déphasages.
