Abstract:
    The invention relates to a delay phase-lock ring, voltage-control delay line and delay unit, wherein it comprises bias generator and voltage-control delay line; the bias generator generates bias voltage input into voltage-control delay line; the delay line generates time delay; the delay line comprises one or more cascade delay units; said delay unit comprises one asymmetry active load delay unit, the first controller, differential signal output select channel and second controller; only one of first and second controllers can be operated at one time. The invention can flexibly set delay output of voltage-control delay line.
