Abstract
Circuitos y métodos para reducir el coste y/o consumo de energía de un terminal de usuario y/o la pasarela de un sistema de telecomunicaciones (550) que pueden incluir un satélite de telecomunicaciones. Las realizaciones generan una señal de polarización de entrada dinámica basada en una envolvente de señal de información (que puede predistorsionarse) que se aplica a la entrada de señal de un amplificador de potencia (AP), y de esta manera reducir el consumo promedio de energía. Otras realizaciones además incluyen la linealización dinámica (518) de la señal de información y/o variación de la tensión de alimentación para el amplificador de potencia (AP) como una función de la envolvente de la señal de información. Otro aspecto es un circuito de alimentación de tensión regulada de realimentación "en cadena" de múltiples etapas para proveer dos o más tensiones de salida que pueden usarse como tensiones de alimentación alternativas para un amplificador de potencia (AP).
