PLL Noise Simulation (How to rad^2/Hz --> V^2/Hz)
Jul 12th, 2007, 2:40pm
 
I am trying to simulate a phase noise of the PLL. I have followed the instructions specified in the “Predicting the Phase Noise and Jitter of PLL-Based Frequency Synthesizers”.
I have used the netlist shown in LISTING 1.

My understanding is that the Noise Output of this simulation is in rad^2/Hz. How do I change it back to V^2/Hz. I would like to compare the simulated data to the measured data.


Thanks for the help,

Aleksey

Hi, Aleksey,

Just multiply the signal power to change back to V^2/Hz as long as the amplitude noise is not large.
