Methods, circuits, devices, and systems are provided for phase locked loop (PLL) locking. A method of locking a PLL includes locking a delay locked loop (DLL) path while applying a control voltage of the DLL path to a loop filter of the DLL path. The method includes locking a DLL voltage while applying the control voltage of the DLL path to the loop filter of the DLL path. The method also includes transferring the control voltage from the loop filter of the DLL path to a loop filter of the PLL path after the DLL voltage locks.
