Abstract

a presente revelação inclui circuitos e métodos para amplificadores de potência. em uma modalidade, um estágio de amplificador principal e um estágio de amplificador de pico de um amplificador de potência recebem uma tensão de fornecimento modulada. o estágio de amplificador de pico é polarizado dinamicamente para ajustar a polarização do estágio de pico para compensar as alterações na tensão de fonte de alimentação. uma tensão de polarização pode ser aumentada conforme a tensão de fornecimento no estágio de pico diminui, e a tensão de polarização pode ser diminuída conforme a tensão de fornecimento no estágio de pico aumenta. consequentemente, as características de polarização do estágio de pico são mantidas ao longo de variações de tensão de fornecimento, e a eficiência do amplificador de potência é aprimorada.
