Abstract

Un circuit logique conforme à l'invention comprend au moins un circuit-porte logique à seuil à plusieurs entrées logiques pondérées et une entrée fixe pondérée déterminant le seuil. Chaque circuit-porte est formé par un premier et un second transistor formant bistable dont l'état est déterminé par la différence de grandeur entre le courant de polarisation total fourni à la base du premier transistor et le courant de polarisation total fourni à la base du second transistor. Des dispositifs injecteurs de courant fournissent des courants de polarisation aux bases des transistors, certains de ces injecteurs étant associés à des entrées logiques du circuit-porte pour fournir un courant de polarisation fonction de la pondération souhaitée de l'entrée, et au moins un de ces dispositifs injecteurs étant associé à une entrée fixe qui sert à déterminer le seuil. Application aux circuits logiques.
