摘要：
A fully integrated high efficiency 10-GHz class-E power amplifier prototype is demonstrated in CMOS 90-nm technology. It reaches an output power of 11.7 dBm, an output 1 dB compression point of 10.32 dBm, and a power-added-efficiency of 40.36% with a supply voltage of 1.5 V. A multiple-output DC-DC converter is proposed to provide several different regulated voltages to the power amplifier to optimize the efficiency at different power levels, and can be further extended as part of an envelope elimination and restoration system.
