PSS analysis for Voltage controlled oscillator

[Rames52]

Why we have to analyze PSS before analysing PNOISE?

Can anyone tell me difference between PSS and PNOISE analysis?

Why we have to analyze PSS before analysing PNOISE?

I think PNOISE needs the steady-state solution to start.

All the analysis starting with P needs the PSS analysis first.

PSS is finding the harmonic frequencies and their magnitudes for your circuit. PNOISE is then evaluating the noise of those harmonics.
