Hi,

I want to plot the Gaussian probability density function for the standalone VCO, to track the distribution of phase variations (jitter) over a time span Δ(T), in presence of thermal noise.

It would be really helpful if someone can guide me regarding the simulation & relevant statistical analysis equations for the above problem.

Thanks in advance,
Himali.

PS: I am using a 3 stage ring oscillator type VCO.
