Title (EN) POWER SUPPLY FOR CLASS G AMPLIFIER
(FR) ALIMENTATION ÉLECTRIQUE POUR UN AMPLIFICATEUR DE CLASSE G
Abstract:
(EN) A Class G amplifier system including a processing unit configured to receive an input signal and output a delayed processed input signal, a class G amplifier configured to receive the delayed processed input signal, and a power supply. The power supply includes a regulator configured to operate in a plurality of configurations, each configuration outputs a different supply voltage to the class G amplifier and a control circuit configured to receive the input signal and determine the supply voltage required from the regulator when the delayed processed input signal is received at the class G amplifier, and output a signal to the regulator to indicate the required configuration for the required supply voltage.
(FR) La présente invention concerne un système d'amplificateur de classe G qui comprend une unité de traitement configurée de sorte à recevoir un signal d'entrée et à émettre un signal d'entrée traité retardé, un amplificateur de classe G configuré de sorte à recevoir le signal d'entrée traité retardé, et une alimentation électrique. L'alimentation électrique comprend un régulateur configuré de sorte à fonctionner dans une pluralité de configurations, chaque configuration transmet une tension d'alimentation différente à l'amplificateur de classe G et un circuit de commande configuré de sorte à recevoir le signal d'entrée et à déterminer la tension d'alimentation requise par le régulateur lorsque le signal d'entrée traité retardé est reçu au niveau de l'amplificateur de classe G, et à transmettre un signal au régulateur pour indiquer la configuration requise pour la tension d'alimentation requise.
