Title: DLL transfer function
Post by nandy on Mar 23^rd, 2008, 12:28pm

Hi all
I would like to know the loop gain of a typical charge pump DLL. Also, I have seen the gain term K_VCDL being used often, but dont know its exact meaning. Does it depend on the number of delay stages in the DLL?

And does this K_VCDL have an upper or lower limit? Im guessing it doesnt as a charge pump DLL is a 1st order system.
