Abstract:
    The invention relates to a lagging comparer, wherein it comprises current source I1, two input MOS tubes, three load MOS tubes, and lagging adjuster for adjusting the threshold value of comparer. When the input MOS tube is NMOS tube, the load MOS tube uses PMOS tube; the single threshold value of circuit is irrelative to the circuit element parameters, that one fixed input voltage of comparer can fix single threshold value; the inventive circuit has asymmetry positive feedback circuit to form the lagging circuit of lagging comparer, to generate threshold voltage and complete comparison. The invention also has positive feedback branch and output branch, MOS tube with static protection and resistance.
