摘　　要：提出了一种基于PSS+PXF的ISF的相位噪声模型,用于预测振荡器的相位噪声。该模型相对传统的拉扎维模型考虑了振荡器的非线性时变特性,因此更加精确。通过仿真验证了该模型的有效性,基于PSS+PXF的ISF的相位噪声模型精度相比传统拉扎维模型提升200%以上。This paper proposes a phase noise model of ISF based on PSS+PXF to predict the phase noise of the oscillator.Compared with the traditional Lazavi model,the model takes into account the nonlinear time-varying characteristics of the oscillator,so it is more accurate.The effectiveness of the model is verified through simulation.The phase noise model precision of the ISF based on PSS+PXF is more than 200%higher than that of the traditional Razavi model.
