ABSTRACT:
A voltage comparator circuit suitable for a semiconductor integrated circuit device comprises a pair of time constant circuits each of which includes a variable impedance, such as a depletion type MISFET, and a capacitor, the variable impedance being controlled by input voltages which are to be compared with one another and a flip-flop circuit which is stabilized to predetermined values on the basis of the comparison between the time variations of the outputs of the time constant circuits.
