Abstract
Circuit générateur de signaux d'horloge Le circuit comprend une première branche formée de 1+2n1 circuits inverseurs en cascade et une seconde branche de 1+2n2 inverseurs également en cascade. Les signaux d'un oscillateur appliqués en 12 et 14 sont retardés proportionnellement de sorte qu'en +C1 et +C2 des trains de signaux d'horloge sont délivrés. Utilisable dans les systèmes de traitement de l'information.
