Abstract

Commutateur C-MOS protégé contre les surtensions parasites et les défauts de polarisation. La tension de polarisation de substrat Vss ou VDD de chaque transistor de commutation est appliquée par l'intermédiaire d'un transistor de même type T5 pour le transistor TN à canal N et T6 pour Tp à canal P. En l'absence de polarisation, la tension source-substrat d'un transistor est ainsi insuffisante pour permettre son déblocage par une tension d'entrée négative parasite. L'entrée et la sortie sont protégées contre des tensions positives ou négatives excessives par des diodes de protection D7 à 10 les reliant à des tensions inférieures aux tensions de polarisation Vss -IV, VDD -1V. Application aux matrices de commutateurs C-MOS intégrés constituant les points de croisement d'un réseau de connexion téléphonique.
