Title (EN) PULSE-WIDTH MODULATION (PWM) WITH INDEPENDENTLY ADJUSTABLE DUTY CYCLE AND FREQUENCY USING TWO ADJUSTABLE DELAYS
(FR) MODULATION D'IMPULSIONS EN DURÉE (PWM) À RAPPORT CYCLIQUE ET FRÉQUENCE INDÉPENDAMMENT AJUSTABLES À L'AIDE DE DEUX RETARDS AJUSTABLES
Abstract:
(EN) A pulse width modulation circuit may generate an adjustable output signal that periodically transitions between a first and a second state with an adjustable duty cycle. A first pulse generator circuit may be configured to generate a first pulse signal that periodically transitions at an adjustable delay with respect to a periodic reference signal. A second pulse generator circuit may be configured to generate a second pulse signal that periodically transitions at an adjustable delay with respect to the periodic reference signal. A logic circuit may be configured to generate the adjustable output signal based on both the first and the second pulse signals.
(FR) L'invention porte sur un circuit de modulation d'impulsions en durée (PWM) qui peut générer un signal de sortie ajustable qui effectue des transitions périodiques entre des premier et second états avec un rapport cyclique ajustable. Un premier circuit générateur d'impulsion peut être configuré pour générer un premier signal impulsionnel qui effectue des transitions périodiques à un retard ajustable par rapport à un signal de référence périodique. Un second circuit générateur d'impulsion peut être configuré pour générer un second signal impulsionnel qui effectue des transitions périodiques à un retard ajustable par rapport au signal de référence périodique. Un circuit logique peut être configuré pour générer le signal de sortie ajustable sur la base à la fois des premier et second signaux impulsionnels.
