Abstract

본 발명은 이동통신단말기에서 출력 효율을 높이기 위한 장치 및 방법에 관한 것이다. 이때, 이동통신단말 장치는, 입력 신호의 포락선 성분을 변조하여 전력을 생성하는 공급 변조기(supply modulator)와, 상기 공급 변조기에서 생성된 전력을 콜렉터(collector)/드레인(drain)의 전원으로 사용하여 상기 입력 신호의 위상 성분을 증폭하는 전력 증폭기를 포함하여 구성되며, 상기 공급 변조기는, 상기 이동통신단말 장치의 배터리 전원을 승압시키는 DC-DC 변환기와, 상기 DC-DC 변환기에서 승압된 전원을 이용하여 출력 전압을 결정하는 전압 레귤레이터(voltage regulator)와, 상기 이동통신단말 장치의 배터리 전원을 이용하여 출력 전류를 결정하는 전환 레귤레이터(switching regulator)를 포함한다.
