tdnoise or pnoise?

PeppeW90

Hi,

I'm simulating a test bench consisting of a crystal oscillator, followed by several inverter stages that act as buffers.

I want to simulate the phase noise at the output of the last buffer, and eventually see how the added buffers contribute to the total phase noise.

What is the most accurate analysis to do in this case? PSS+PNOISE(sources option) or PSS+PNOISE(timedomain option)?

I don't want to see the integrated jitter or the noise in V^^2/Hz, but the phase noise at the output of the last buffer.

Thanks

    Until now, I used PSS+PNOISE (Sources), is this accurate?
