CA 2623941

Various embodiments described herein relate to a power management block and an amplification block used in the transmitter of a communication subsystem. The power management block provides improved control for the gain control signal provided to a pre-amplifier and the supply voltage provided to a power amplifier which are both in the amplification block. The power expended by the power amplifier is optimized by employing a continuous control method in which one or more feedback loops are employed to take into account various characteristics of the transmitter components and control values.

Divers modes de réalisation décrits ici portent sur un bloc de gestion de puissance et un bloc d'amplification utilisés dans l'émetteur d'un sous-système de communication. Le bloc de gestion de puissance fournit une commande améliorée pour le signal de commande de gain adressé à un préamplificateur et la tension d'alimentation adressée à un amplificateur de puissance qui sont tous deux dans le bloc d'amplification. La puissance développée par l'amplificateur de puissance est optimisée en employant un procédé de commande continu dans lequel une ou plusieurs boucles de rétroaction sont employées pour prendre en compte diverses caractéristiques des composants d'émetteur et des valeurs de commande.
