1. , for providing a device for output signal, comprising:

  • Pierce circuit, is configured to provide oscillator signal;

    Comparator, is configured to described oscillator signal and adjustable threshold to compare to provide described output signal;

    AndThreshold circuit, be configured to produce described adjustable threshold to deflect the phase place of described output signal to follow the tracks of the phase place of another signal, and wherein, by described output signal and phase place tracked described in another signal compare and judge whether to need the phase place by regulating described adjustable threshold to change described output signalWherein, described device comprises further;

    At least one other comparator, is configured to the output signal described oscillator signal and at least one other adjustable threshold being compared to provide at least one other;

    Wherein, described threshold circuit is configured to further;

    produce at least one other adjustable threshold described to deflect at least one other output signal described the phase place of each,Wherein, described device comprises further;

    Data storage, is configured to storage one group of adjustable door limit value, and each in this group adjustable door limit value offsets with an out of phase and is associated;

    Wherein, described threshold circuit is configured to further;

    select at least one in this group adjustable door limit value to deflect the phase place of described output signal.
