In PLL, PFD( phase frequency detector) are mostly used. PD are usually used in DLL. I have some questions on the usage of PD, which I could not find answers in books and papers.
what is the locking range of a PD PLL, for example, a mixer used as PD. I tried to analyze the locking range of PD PLL, but failed. what is the advantage and disadvange of using PD instead of PFD? For example, we generally use PD in a DLL, why do not use PFD in a DLL?
Thanks.
