然后从反馈振荡器的李森模型出发,重点分析了科尔皮兹振荡器的相位噪声,通过MATLAB和VC++的混合编程得出QL是C2的单调递增函数。
Then the phase noise of Colpitts oscillator circuit is analysed on the basis of phase noise equation of Leeson model in feedback oscillator and we can draw a conclusion that QL is a monotone increasing function of C 2 by MATLAB and VC + + .
