摘要
2.4GHz功率放大器采用标准薄氧化物晶体管，采用1.2V, 0.13 μ m CMOS工艺。输出匹配网络完全集成在芯片上。在-1dB压缩点，PA传输高达24dBm的线性功率，漏极效率为25%。当驱动到饱和状态时，它传输27dBm峰值功率，漏极效率为32%。提出并论证了一种提高平均效率的方法。该技术不会降低峰值功率时的瞬时效率，并在功率回退时保持恒定的功率增益
A 1.2V, 2.4GHz Fully Integrated Linear CMOS Power Amplifier with Efficiency Enhancement
A 2.4GHz power amplifier is implemented with standard thin-oxide transistors in a 1.2V, 0.13 mum CMOS process. The output matching network is fully integrated on chip. The PA transmits up to 24dBm linear power with 25% drain efficiency at -1dB compression point. When driven into saturation, it transmits 27dBm peak power with 32% drain efficiency. A technique for enhancing average efficiency is proposed and demonstrated. This technique does not degrade instantaneous efficiency at peak power and maintains constant power gain with power back-off
