What's the methods to simulate Phase Noise of PLL?

[konkon]

You can use the PSS analyses in spectreRF to do the frequency VS voltage sweep for VCO, use the Pnoise analysis to do the PN analysis for the frequency which you want.
Hspicerf can do the same thing as SpectreRF.

Hi,


Here you can download some Excel spreadsheets to calcumate the noise.

Hi friends,
If u want to see eye diagram of pll in HSPICE easily,
use cosmo scope(or called cscope).

PN(phase noise) u said, is shown as jitter of PLL, so u will see the jitter through eye diagram of PLL output in cscope.

thanks.

do you have some infor

I haven't had good experience with using these RF tools for full PLL jitter sim. Typically it is much easier to get phase noise of individual blocks and then create the total PLL jitter through filtering and integration.
