Title

(EN) SYSTEM AND METHOD FOR FAIL-SAFE GENERATION OF A RECTANGULAR WAVE SIGNAL

(FR) SYSTÈME ET PROCÉDÉ DE GÉNÉRATION À SÉCURITÉ INTÉGRÉE D'UN SIGNAL D'ONDE RECTANGULAIRE

Abstract

(EN) Herein is disclosed a fail-safe circuit for generating a rectangular wave having a desired duty cycle, the circuit comprising: first and second duty cycle registers configured to output first and second parallel duty cycle signals each representing the desired duty cycle; a binary counter configured to generate a parallel counter signal; first and second comparators configured to generate first and second duty cycle rectangular waves; first and second supervisors configured to generate first and second supervisor signals; and a combining circuit configured to generate an output rectangular wave from the first and second duty cycle rectangular waves, and the first and second supervisor signals.

(FR) L'invention concerne un circuit à sécurité intégrée destiné à générer une onde rectangulaire ayant un cycle de service souhaité, le circuit comprenant : des premier et second registres de cycle de service conçus pour délivrer des premier et second signaux de cycle de service parallèles représentant chacun le cycle de service souhaité ; un compteur binaire conçu pour générer un signal de compteur parallèle ; des premier et second comparateurs conçus pour générer des première et seconde ondes rectangulaires de cycle de service ; des premier et second superviseurs conçus pour générer des premier et second signaux de superviseur ; et un circuit de combinaison conçu pour générer une onde rectangulaire de sortie à partir des première et seconde ondes rectangulaires de cycle de service, et des premier et second signaux de superviseur.
