Abstract

Abstract Translated from French L'invention concerne un inverseur logique rapide, en circuit intégré, à source unique d'alimentation, utilisant les transistors à effet de champ du type "quasi-normalement bloqué", et les opérateurs logiques à plusieurs entrées et à plusieurs sorties qui en dérivent. Dans une réalisation de l'invention (figure 6) on est parti d'un inverseur à entrée par diode (DS) sur grille de transistor à effet de champ (T1), à sortie sur la source d'un transistor à effet de champ (T21). Ce schéma ds base a été enrichi en dotant l'entrée (entre pôle d'alimentation et borne d'entrée) de deux paires de diodes aboutissant aux grilles d'un transistor bigrille (T1), et en réalisant des sorties indépendantes (S1, S2...) obtenues en reliant les grilles de transistors montés en drain commun sur le pôle de l'alimentation distinct de la masse. Application à la logique rapide sur arséniure de gallium. The invention relates to a fast logic inverter, in integrated circuit, with a single supply source, using the field effect transistors of the "quasi-normally blocked" type, and the logical operators with several inputs and with several outputs derived therefrom. . In one embodiment of the invention (FIG. 6), we started with an inverter with diode input (DS) on a field effect transistor gate (T1), with an output on the source of a field effect transistor. (T21). This basic diagram has been enriched by providing the input (between supply pole and input terminal) with two pairs of diodes leading to the gates of a bigrile transistor (T1), and by producing independent outputs (S1, S2 ...) obtained by connecting the grids of transistors mounted in common drain on the power supply pole separate from the ground. Application to fast logic on gallium arsenide.
