I am running into a very weird issue when calculating the phase noise of my PLL in cadence. The bandwidth of my filter is too large, even though I am calculating the loop filter parameters (Cp Rp C2) using zeta and natural frequency formulas from Razavi's book. Please see the attached image. Can someone suggest any ideas to resolve or troubleshoot this issue. Also, attaching the block diagram of my PLL for reference. Thank you for any help!!
