摘要：A comparator comprises a current mirror, a differential input pair, and a auxiliarycircuit. The current mirror has a biasing end coupled to a power voltage, a first end, and acurrent outputting end coupled to an output node of the comparator. The differentialinput pair has a first and second input ends for respectively receiving a first voltage and a

second voltage, a second and third ends, and a ground end, wherein the third end iscoupled to the first end. The auxiliary circuit is coupled between the output node and thesecond end, and provides a minimum voltage of a comparison result output at the outputnode. The comparison result is the power voltage when the first voltage is larger thanthe second voltage, and the comparison result is the minimum voltage when the firstvoltage is less than the second voltage.
