摘要：

We present in this paper a high-efficiency Class-E polar power amplifier (PA) with a novel digitally-controlled output matching network (OMN). The OMN varies the load impedance seen by the PA to modulate the amplitude of the output signal. It performs the modulation while simultaneously achieving a high power-efficiency by attaining an approximate zero-voltage-switching condition at the PA, and mitigating the load mismatches. The proposed PA embodying the OMN is designed using the TSMC 40 nm CMOS technology. Simulation results at 2.4 GHz and 1.1 V supply show that the PA achieves a 48% power-efficiency at peak output power of 17 dBm.
