Abstract
Circuit à dispositifs Josephson permettant la réalisation d'amplificateurs et de circuits logiques. Un courant d'injection, en sus du courant de porte, est injecté, ou induit, en un point du circuit dont la valeur est telle que la non linéarité de la caractéristique de commutation s'en suit Une modification du courant d'injection, du courant porte, du point d'injection, et de l'inductance permettent l'obtention de la caractéristique souhaitée. Utilisable comme circuits logiques et amplificateurs.
