Hi,

Im trying to measure the phase noise of my driven clock circuit.

After following the tutorials from Cadence, Im doing PSS analysis followed by PNOISE analysis with time-averaged option for pahse noise. I am able to get the phase noise plot which is in dBc/Hz curve in log scale.

From here, Im able to use marker to get the Noise Flooe in dBc/Hz after the curve flattens.

Problem Statement : How can I measure integrated phase noise in dBc for defined integration limits ?

Case1 : to get the curve to calculator and find the area under the curve mathematically. Can anyone help me how to do it?

Case2 : Im using Printed Noise Summary to get integrated Noise but it has only V2 and V units but I need it in dBc. Can anyone help me how to do this?

Its a bit urgent, looking forward to your response.
