This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...

While analog phase-lock loops (PLLs) still have a home in communication equipment, there is a clear shift in the sector toward implementing digital PLLs (DPLLs) in comm ASIC designs. For example, in ...

A fuzzy tracking system performs as a narrow bandwidth tracking system in terms of noise reduction, and a wide bandwidth tracking system in terms of dynamic response, overcoming the contradiction ...
