Abstract

L'invention concerne un circuit porte. Selon l'invention, il comprend un premier moyen formant porte 6 normalement à l'état non passant; un second moyen formant porte 7 connecté dans une trajectoire de signaux et normalement à l'état passant; un moyen pour appliquer un signal de commande P au premier moyen formant porte pour le rendre passant, et permettre ainsi au second moyen formant porte d'être coupé; et un moyen limiteur 8 pour maintenir un potentiel d'entrée du second moyen formant porte inférieur à son potentiel de sortie. L'invention s'applique notamment aux circuits de suppression du bruit.
