PURPOSE: A CMOS output voltage limit circuit is provided to provide a CMOS output voltage limit circuit which is suitable for a CMOS process by implementing all components in the CMOS process. CONSTITUTION: A comparator generates a comparison signal by comparing a voltage of an input signal with a limit voltage. The comparison signal has a logic state according to a comparison result of the limit voltage and the voltage of the input signal. According to the logic state of the comparison signal, a switching unit outputs any one of the input signal and the limit voltage as a selection signal. An amplifier generates an output signal by amplifying the selection signal.
