RF MULTIPLE OUTPUT SUPPLY GENERATOR FOR RF POWER AMPLIFIERS USING DIFFERENTIAL CAPACITIVE ENERGY TRANSFER

rf 전력 증폭기(PA)를 포함하는 무선 주파수(rf) 증폭기의 효율을, "공급 변조"("드레인 변조" 또는 "콜렉터 변조"라고도 함)를 통해 증가시키는 회로 및 기술이 기재되고, rf 증폭기에 제공된 공급 전압은 합성되는 rf 신호에 의존하여 시간 경과에 따라 동적으로 조절("변조")된다. 최대 효율 개선을 위해, 공급 전압은 이산 전압 레벨 사이에서 또는 짧은 시간 스케일로 연속적으로 조절될 수 있다. 또한, rf 증폭기에 제공된 공급 전압(또는 전압 레벨)...

description rf 전력 증폭기(PA)를 포함하는 무선 주파수(rf) 증폭기의 효율을, "공급 변조"("드레인 변조" 또는 "콜렉터 변조"라고도 함)를 통해 증가시키는 회로 및 기술이 기재되고, rf 증폭기에 제공된 공급 전압은 합성되는 rf 신호에 의존하여 시간 경과에 따라 동적으로 조절("변조")된다. 최대 효율 개선을 위해, 공급 전압은 이산 전압 레벨 사이에서 또는 짧은 시간 스케일로 연속적으로 조절될 수 있다. 또한, rf 증폭기에 제공된 공급 전압(또는 전압 레벨)은 rf "트래픽" 변동에 대해, 데이터 전송 오류를 최소화하기 위해 트랜스미터 출력 강도의 적합화와 관련된 것과 같은 소망의 rf 엔벨로프의 장기간 변화를 수용하도록 적합화될 수 있다. Described are circuits and techniques to increase the efficiency of radio-frequency (rf) amplifiers including rf power amplifiers (PAs) through "supply modulation" (also referred to as "drain modulation" or "collector modulation"), in which supply voltages provided to rf amplifiers is adjusted dynamically ("modulated") over time depending upon the rf signal being synthesized. For the largest efficiency improvements, a supply voltage can be adjusted among discrete voltage levels or continuously on a short time scale. The supply voltages (or voltage levels) provided to an rf amplifier may also be adapted to accommodate longer-term changes in desired rf envelope such as associated with adapting transmitter output strength to minimize errors in data transfer, for rf "traffic" variations.
