ABSTRACT:
A voltage comparator comprises a first pair of series-connected CMOS transistors and a second pair of series-connected CMOS transistors which are respectively connected in parallel between power supply terminals and clocked by a common clock pulse. A first MOS transistor having its gate supplied with a reference voltage is connected between the first paired CMOS transistors. A second MOS transistor having its gate supplied with an input voltage to be compared with the reference voltage is connected between the second paired CMOS transistors. An RS flip-flop circuit is provided which has a pair of inputs connected to the drains of the first and second MOS transistors, respectively.
