Hi,
I am trying to simulate the phase noise of a clock receiver block. It is a complex block, but you can imagine as a cascade of various buffers which are biased by some other biasing blocks (which work in DC).
The operating frequency is 10 GHz.
I'm running a PSS with the following settings:
-beat frequency=10GHz
-oversample factor: none
-number of harmonics: 10
Accurancy defaults (errpreset): Conservative
All the other are left blank.
I'm running a PNOISE after with the following settings:
Sweeptype: Default
Start-Stop: 1k-10M
Maximum Sidebands: 10
Output: Voltage (and I selected the nodes to calculate the PN)
Input source: None
Noise Type: Sources
The question is: What is the method to verify that the phase noise I'm getting is accurate enough? Is there any parameter to change and confirm that results are the same?
