ABSTRACT:
Locked loops, delay lines and methods for delaying signals are disclosed, such as a delay line and delay lock loop using the delay line includes a series of delay stages, each of which consists of a single inverting delay device. The inputs and outputs of a selected stage are applied to a phase inverter that inverts one of the signals and applies it to a first input of a phase mixer with the same delay that the other signal is applied to a second input of the phase inverter. The delay of the signals from the selected delay element are delayed from each other by a coarse delay interval, and the phase mixer interpolates within the coarse delay interval by fine delay intervals. A phase detector compares the timing of a signal generated by the phase interpolator to the timing of a reference clock signal applied to the delay line to determine the selected delay stage and a phase interpolation value.
