Hello,

I'm new to PLL analysis. I try to analyze the output noise. How can I plot the output spectrum and see the reference spurs and other noise parts?

I use HSPICE and post-process signals in MATLAB.

Thanks for you help and suggestion.
 

There are some MatLab and MathCad routines that calculate the Gain and Phase Response of the PLLs.
You may use them to plot the response..Output Spectrum can not be plotted but measured...
