摘要

利用Volterra分析方法分析了小信号CMOS共源放大器级的高频非线性失真与偏置、源端和负载端阻抗以及5 GHz谐波的关系。预测结果与偏置、源和负载阻抗的测量结果非常吻合。研究结果可应用于低功耗无线射频电路设计。

Analysis of optimized input and output harmonic termination on the linearity of 5 GHz CMOS radio frequency amplifiers

The high-frequency nonlinear distortion of a small-signal CMOS common-source amplifier stage is analyzed as a function of bias, source and load termination impedance, and harmonics at 5 GHz using a Volterra analysis. The predictions closely match measurements over bias, and source and load impedances. The results can be applied to low-power wireless RF circuit design applications.
