Hi all,
I am a new student working on simulation of phase noise of PLL. Currently I am working on simulation of frequency divider and PFD. However, I don't know why I can't get correct simulation result of phase noise. I got corect result for VCO.
I know for VCO, during my simulation in Pnoise, I can choose Oscillator. However, for divider and PFD, I can't do that. Can anyone tell me how to setup the phase noise simulation for divider and PFD? I can't find information from spectreRF user manual as it only describes simulation of VCO.
Thank, Paul
