缓冲器输出端相位噪声模型分析

相位噪声是振荡器的重要性能指标。近年来,研究人员在振荡器相位噪声表征方面已经做了大量的工作,在这些过程中开发出了很多不同类型的振荡器相位噪声模型。但是在这些模型中,都没有分析缓冲器噪声对振荡器相位噪声的影响。而在研究课题中,首先要对缓冲器噪声的功率谱密度函数进行数学建模,并易于将这个模型嵌入到相位噪声的非线性扰动分析模型,这样就得到了含有缓冲器噪声的振荡器相位噪声模型。

The Analytic Model Of Phase Noise Of The Output Of Buffer

Phase noise is a very important performance of oscillator.Recently much research work is done in the fields of phase noise,and many models of phase noise are developed in the research.However,in these models,the effect of buffer noise on the phase noise of oscillator is not analyzed,while in this project,the power spectral density function of buffer noise is modelled,and this model is easily embedded into the model of nonlinear perturbation analysis model of the phase noise.Thus the model of phase noise con...
