1. pulse period voltage adjuster of peak value in order to the adjustment multi-task signal comprises:

  • First current source is in order to produce one first electric current;

    First switch is controlled the flow of said first electric current according to first pulse width modulating signal;

    AndShunt;

    Shunt the said flow of said first electric current according to differential wave and reference signal;

    To form at least a portion of time flow;

    Wherein, at least a portion of said flow is the electric current summation that flows through first node (Out+) and Section Point (Out-) that said first electric current draws through said shunt shunting;

    Wherein, said differential wave is to obtain according to relative signal intensity pointer and critical voltage, and said peak value is directly proportional with said flow.
