number of noise/freq pairs in pss/pnoise simulation

Hello,

I am using Virtuoso 6.1.7, spectre version 18.10.169.

I am simulating a 32kHz relaxation oscillator with pss/pnoise to get phase noise/jitter. I want to see how phase noise/jitter are affected by noise in supply. Can I simply do that by adding noise/freq pairs in analogLib voltage source as shown in the figure or is it another way?

Kind Regards,

Kostas

If your supply noise is not random noise but rather some kind of interference, you could also use the sampled pxf analysis (see for example https://designers-guide.org/forum/YaBB.pl?num=1187679312).
