Title (EN) PUSH-PULL LINEAR HYBRID CLASS H AMPLIFIER
(FR) AMPLIFICATEUR SYMÉTRIQUE LINÉAIRE DE CLASSE HYBRIDE H
Abstract:
(EN) Several push-pull linear hybrid class H amplifiers are disclosed. A split power rail provides a positive supply rail and a negative supply rail in response to a power supply control voltage. A push-pull amplifier stage is powered by the positive and negative supply rails. The amplifier stage receives an input signal and provides a corresponding amplified output signal. A power supply control circuit provides the power supply control voltage in response to the smaller of the positive and negative supply rails, and the input signal.
(FR) L'invention porte sur des amplificateurs symétriques linéaires de classe hybride H, sur un rail d'alimentation dédoublé produisant un rail positif et un rail négatif en réponse à une tension d'alimentation de contrôle et sur un étage d'amplification symétrique alimenté par le rail positif et par le rail négatif. L'étage d'amplification reçoit un signal d'entrée et produit un signal de sortie amplifié correspondant. Un circuit de commande fournit la tension de commande d'alimentation en réponse au plus petit des rails positif ou négatif, et au signal d'entrée.
