phase detector simulink
i am using simulink to model PLL.
i followed the paper:
Modeling of fractional-N division frequency synthesizers with SIMULINK and MATLAB
Brigati, S.; Francesconi, F.; Malvasi, A.; Pesucci, A.; Poletti, M.;
Electronics, Circuits and Systems, 2001. ICECS 2001. The 8th IEEE International Conference on Volume 2, 2-5 Sept. 2001 Page(s):1081 - 1084 vol.2
i am now follow Fig. 3. to model PFD
it suggest to use H(s) = 1/(DZ/ln2*s + 1), DZ is the dead-zoon time window.
however, i find the output is not reasonable.
anyone did this or give me some suggestion? thanks.
