| 摘 要： | 利用共源共栅电感可以提高共源共栅结构功率放大器的效率。这里描述了一种采用共源共栅电感提高效率的5.25GHz WLAN的功率放大器的设计方法，使用CMOS工艺设计了两级全差分放大电路，在此基础上设计输入输出匹配网络，然后使用ADS软件进行整体仿真，结果表明在1.8V电源电压下，电路改进后于改进前相比较，用来表示功率放大器效率的功率附加效率（PAE）提高了两个百分比。最后给出了功放版图。

| Abstract: | The efficiency of the cascode power amplifier can be boosted by use of cascode-inductance. In this paper, the design of power amplifier using cascode-inductance for 5.25GHz WLAN is described. The method is applied to a full differential two-stage amplifier, and then the input-output matching network is designed. Then the global simulation is completed by the ADS software. The results show that, with 1.8V supply voltage, the power-added efficiency of the improved PA has about two-percent increasement. Finally, the layout of the improved PA is presented. |
