  • Auto-phase synchronization in delay locked loops
    Patent number: 9148157
    Abstract: Tuning circuitry may include a controller that is configured to determine a phase difference for a pair of signals generated at different points in a master delay line of a master-slave delay locked loop (DLL) circuit. One of signals of the pair may be communicated through a slave delay line of the master-slave DLL circuit before the phase difference is determined. A programming delay value used to set a phase delay of the slave delay line may be adjusted or tuned based on the phase difference.
    Type: Grant
