Dear all,
According to Ken's paper of "phase noise and jitter", I need to get the jitter of PFD/CP and FD blocks to determine the overall jitter of the PLL.
Unlike oscillators, for PFD/CP and FD, input signals must be given to get pss and pnoise results. In the paper, it is said "a representive input" should be set for PFD/CP and FD. I wonder how to set the input.
For PFD/CP, a reference and feedback clock act as the input for PFD, should I add some delay between these two signals, how do I set the rise and fall time? For FD, the latter question is also bothering me.
Any answer and discussion is appreciated.
