作为多电平电源调制器瞬态振铃抑制方法的门极脉冲技术

This letter demonstrates a gate pulsing technique to reduce the ringing in multilevel dynamic voltage supplies used for modulating the drain bias of GaN radio-frequency power amplifiers (RFPAs). Supply modulation can improve overall average efficiency when the RFPA is amplifying signals with varying envelopes. Multilevel discrete supply modulators (SMs) are used for high instantaneous bandwidth si...
