[Ngspice-users] About noise analysis

[Akshay K. <kul...@gm...>]

Hello,

This is Akshay Kulkarni and I am currently working on PLL with ngspice.

I was getting the phase noise at the output of PLL and I was not really
sure if the noise analysis that is present in the ngspice can perform that.

My question is -> Does noise analysis in ngspice give out phase noise?

When I ran the noise analysis, I got 2 noise results:
- noise2
- noise3

noise 2 was related to noise spectral density and noise3 was the total
noise in design.

So, are noise2 and noise3 results related to phase noise ?
If not, could you please tell me what are they related to?


Thanks,
Akshay
