摘要

采用tsmc65nm GP CMOS工艺设计了一种带8路流压组合变压器的全集成CMOS功率放大器。针对大功率CMOS放大器的设计，提出了一种新型混合型功率组合变压器。使用四个相同的放大器，它们的输出功率由一个8路电流-电压组合变压器组合。在3.3V电源下，在2.4GHz工作频率下，功率放大器的最大输出功率为35.2dBm，峰值功率增加效率为38.73%。在1dB压缩点，该功率放大器的输出功率高达33.1dBm，功率增加效率为28.8%。

A35.2 dBm CMOS RF Power Amplifier Using an 8-Way Current-Voltage Combining Transformer with Harmonic Control

A fully integrated CMOS power amplifier with 8-way current-voltage combining transformer is performed in tsmc65nm GP CMOS process. For the high power CMOS PA design, a novel hybrid-type power combining transformer is proposed. Four identical PAs are used and their output power are combined by an 8-way current-voltage combining transformer. With 3.3V power supply, the proposed power amplifier provides maximum output power of 35.2dBm and peak power added efficiency of 38.73% at 2.4GHz operating frequency. At 1dB compression point, the proposed power amplifier exhibits high output power of 33.1dBm with power add efficiency of 28.8%.
