ABSTRACT:
A reference voltage generating circuit outputs a reference voltage (used for comparison of magnitude with an analog voltage) at a plurality of levels by using a differential amplifier to amplify voltages at nodes formed by mutually adjacent resisters among a plurality of resistors comprising a ladder resistor unit which is optionally selected by a decoder and an analog switch unit.
