Abstract
L'invention utilise le fait que, dans une triode Gunn, une impulsion très brève sur la grille provoque la formation d'un domaine dipolaire qui se propage jusqu'a l'anode en un temps de l'ordre de la nanoseconde. Dans le dispositif de l'invention, on ajoute des électrodes ou doigts D1 , D2 , etc., entre grille et anode pour matérialiser des états binaires << 1 >> et << 0 >> par application de potentiels respectivement hauts et bas. Sous chaque doigt porté à un potentiel bas, il se crée une charge d'espace qui produit une impulsion négative dans le courant anodique du dispositif Gunn au moment du passage du domaine dipolaire sous le doigt. A une combinaison d'états binaires simultanés correspond donc une série d'impulsions successives. Application aux convertisseurs << parallèle-série >> en teléphonie par multiplexage temporel.
