This brief reports a 0.92-GHz two-stage power amplifier (PA) in 130-nm CMOS process with improved backoff power efficiency and linearity. The two key techniques are: a switching mechanism for adaptive device sizing of the power stage, and a high-Q compact inductor (HQCI). The PA is designed to opera...
