该论文提出了一种基于可重构串/并联正交耦合器的Doherty功率放大器，采用CMOS SOI工艺。通过根据天线VSWR重新配置主/辅助PA的权重和自适应偏置，实现了对负载变化的鲁棒线性度和回退效率优化。
reconfigurations remain the same. In addition, the Main/Aux-PAs role exchange for series/parallel Doherty operation is enabled by setting the bias of two adaptive biasing circuits. Naga Sasikanth Mannem, Min-Yu Huang, Tzu-Yuan Huang, Sensen Li, Hua Wang Depending on the antenna VSWR, the Main/Aux PA weightings are also reconfigured. Each PA output stage comprises 3b-binary-weighted PAs. The weightings are only for static configuration over the antenna VSWR and are NOT dynamically adjusted for modulation signals. The 3b-PA-stage weighting is controlled by the source switches of the common-source (CS) amplifiers, while a shared cascode stage boosts the PA power gain and reverse isolation. Both CS and cascode PAs have capacitance neutralization to improve stability. A parallel inductor at the cascode sources compensates parasitics and improves PAE. The driver stage is a CS amplifier also with capacitive neutralization. For complex
assumption and vice versa. However, the design equations for Main/Aux-PA
