PLL's simulation in simulink

[wjlzhx]

pll simulink

hi
now i'm design a PLL using charge pump
it is a typeⅡ PLL，and
i got Kv=430MHZ/V
Ip=100uA
Rp=24K
Cp=50p
FREFRENCE = 12M
and Fout=96M
so how to calculate ??
and how to simulate in simulink???
and how to modeling the model in simulink ??
does somebody has the book about this???

thanks advance!!!!

You can start by looking at Matlab Central. There are a couple of very useful presentations that cover PLL's

Try this one to start

You seem to have all the interesting things calculated, so the only thing that you need to do is simulate the PLL to make sure it actually works.

pll in simulink

thanks !!
but how do i make sure the f0,fp,and fz????

now someone tell me f0 = 1/20*FREFRENCE
,IS that right????

does somebody can tell me??

check these files , i have created them long time ago "3 years" to simulate the PLL on simulink in both time , and s domain

enjoy

phase locked loop simulink

as u get ur filter componrnts u can plot the bode plot of the filter to get the poles locations

en, your model is very useful and another model proposed a block to detect the frequency

I have an older version of simulink (4 I think).

Does your models take into account phase noise of the vco/dco/nco?

Has anybody made a phase noise plot from simulink pll simulations?

cheers,

no my model didn't model phase noise , but u can adapt it , by adding noise sources , and view the output noise of course use the frequency domain files
and if u do it , upload the modified files

i am planning to add phase noise in the near future but i don't have time these days
