Title: Wrong magintude of Bode plot with Aktas's behavioral model
Post by vence on Jun 28^th, 2008, 12:43am

I just tried the behavioral model of PLL-open loop from book and dissertation of Adem Aktas.

The phase of ac response seems okay, but the result on magnitude seems wrong. I can't find what's wrong with it. Can anyone help me?

Parameters are given below:
Rz=94K
Cz=25.6p
Cp=3.2p
N=192
Kvco=2*pi*100e6
Kp=30e-6
