I am having some difficulty simulating the PFD/CP noise. I have the output noise of the charge pump in PSS (after setting the phase difference b/w ref and feedback to 0). The transfer function from here to PLL output should be N/Kphi. But, I am getting unrealistic results if I do this. Any ideas on what I am doing wrong?
