phase noise to jitter conversion
Hi,
I have an RC oscillator circuit for which I need to calculate the Peak-peak cycle jitter. I am using Spectre simulator. But I cannot just run a transient analysis and find the same since the models I am using does not comprise the noise component. Hence I am running a pss-pnoise analysis to find the phase noise. And from the phase noise I would like to calculate the jitter value. I got the phase noise graph. Now to convert it to jitter, I need to integrate this graph(find the area) over a certain frequency range. This is in accordance with a reference document which explains the conversion of phase noise to jitter. But the frequency range to be considered for integration has not been explained clearly. Can any of you help me in proceeding further; atleast in calculating the accumulated rms jitter?
