摘要

本文介绍了一种全集成放大器的反馈线性化设计。仿真结果表明,S21的峰值功率增益为10.3 dB,单位增益带宽为16 GHz,优于- 10 dB S11。仿真结果表明,在输出功率为−10 dBm时,IIP3提高了7 dB, IM3提高了18 dBc。利用导数叠加提高了反馈放大器的宽带线性度,从而提高了其动态范围。采用0.13μm CMOS技术设计了全集成放大器反馈线性化电路。

Fully-integrated amplifier feedback linearization design analysis
In this paper, the design of a fully-integrated amplifier feedback linearization is presented. Simulation results have yielded a peak S21 power gain of 10.3 dB and a unity gain bandwidth of 16 GHz with better than −10 dB S11. The simulation results show a 7 dB IIP3 improvement and IM3 improvement of 18 dBc at output power of −10 dBm. Using derivative superposition improves the feedback amplifier broadband linearity and in turn improves its dynamic range. The proposed fully-integrated amplifier feedback linearization was designed using the 0.13μm CMOS technology.
