  • Patent number: 7564285
    Abstract: A controllable delay line includes an anti-jitter unit, a dependent current source, a first current mirror, a second current mirror, a regulation capacitor, a compensation capacitor and an output buffer unit. The anti-jitter unit receives a first bias voltage and produces a second bias voltage based on the first bias voltage. When the voltage source used in the controllable delay line has a variation, the second bias voltage varies therewith. The regulation capacitor is used for reducing the variation of the voltage difference between the voltage source and a node voltage of the first current source. The compensation capacitor is used for reducing the influence of a transition of the input signal of the output buffer unit on the node voltage, so as to lower the jitter amount of the output signal of the output buffer unit.
