Abstract:
An integrated circuit includes: a reference voltage generation unit configured to be driven in response to an enable signal, select one of a plurality of reference voltages generated by dividing a power supply voltage as an input reference voltage, and output the input reference voltage; and a reference voltage level compensation unit configured to be driven in response to the enable signal and change a level of the input reference voltage by an amount of change in a level of an external voltage.
