摘要

提出了一种适用于TSMC 0.18 μm无线体域网络(WBAN)的3- 7ghz AB级两级功率放大器的设计方案。为了最大限度地提高功率附加效率，采用了源和负载-拉轮廓。布置图后仿真结果表明，UWB-PA的功率增益(S21)为12 dB±0.8;在3ghz ~ 7ghz频率范围内，输入回波损耗(S11)小于- 10db，输出回波损耗(S22)小于- 11db。此外，该PA在5ghz时实现了38.5%的最大功率附加效率(PAE)，在相同频率下实现了7.21 dBm的输出1db压缩。此外，通过感兴趣的频段实现了±32.5 ps的群延迟变化。

A high efficiency 3–7 GHz class AB CMOS power amplifier for WBAN applications

The design of 3-7 GHz class AB two stages power amplifier (PA) for wireless body area network (WBAN) applications in TSMC 0.18 μm is presented. Source and Load-pull contours are employed in order to maximize power added efficiency. The post-layout simulation results of the proposed UWB-PA indicated that the power gain (S21) is 12 dB ± 0.8; the input return loss (S11) and the output return loss (S22) are less than -10 dB and -11 dB respectively over the frequency range from 3 GHz to 7 GHz. In addition, The PA achieved maximum power added efficiency (PAE) of 38.5% at 5 GHz and an output 1-dB compression of 7.21 dBm at the same frequency. Moreover, a group delay variation of ± 32.5 ps was achieved through the frequency band of interest.
