Abstract

Circuit d'inversion du sens du courant dans une charge. Deux des branches du pont comprennent chacune un dispositif Josephson J1, J2 commuté à tour de rôle par les commandes 12 et 13 respectivement Sur chaque dispositif est monté en parallèle un circuit formé de l'enroulement secondaire 4 (5, d'un transformateur en série avec une jonction Josephson supplémentaire J3 (J4) de sorte qu'un courant vienne annuler le courant Ig1 (Ig2) circulant dans J1 (J2). Utilisable dans les circuits logiques ou les mémoires de données requérant deux sens de courant
