Abstract

Circuit de décodage utilisant des jonctions Josephson. Le courant d'entrée Ig traverse ou non la ligne L1 selon l'état de conduction du dispositif Josephson J1. Le courant IL1 commande les 2 dispositifs Josephson J2, J3 associés à des circuits identiques au circuit de l'entrée. Une paire J2, J3 constitue l'étage 1. Cet étage possède 2 boucles de décodage, chacune étant placée dans la branche 7 d'une boucle d'adressage 8, chacune des branches comportant une porte d'adressage A1 et A1 qui commande le courant dans J2 et J3. Utilisable dans les mémoires en vue de l'adressage de leur contenu.Decoding circuit using Josephson junctions. The input current Ig either crosses the line L1 or not depending on the conduction state of the Josephson J1 device. Current IL1 controls the 2 Josephson devices J2, J3 associated with circuits identical to the input circuit. A pair J2, J3 constitutes stage 1. This stage has 2 decoding loops, each being placed in branch 7 of an addressing loop 8, each of the branches comprising an addressing gate A1 and A1 which controls the current in J2 and J3. Can be used in memories for addressing their content.
