A MOS integrated circuit includes: a voltage-to-current conversion circuit configured to convert first and second voltages to a first current having a current value corresponding to the first voltage and a second current having a current value corresponding to the second voltage; and a current comparison circuit configured to compare the respective current values of the first and second currents and to output a voltage showing the comparison result. Oxide films of MOS transistors of the current comparison circuit are thinner than oxide films of MOS transistors of the voltage-to-current conversion circuit.
