Abstract :
The tracking accuracy of baseband Delay Locked Loop (DLL) with narrow loop band is studied. The equivalent phase discrimination model of code delay correlator is provided, and the correlation functions and power spectrum density functions of correlator output port noise and its equivalent noise at the input port are developed, then the simplified calculation equation of the tracking accuracy of linear DLL with narrow loop band is deduced.
