Abstract
A start-up circuit for a reference voltage generator which restarts a reference voltage generating circuit when a reference voltage drops below a predetermined level due to noises or change of a power supply voltage. The start-up circuit according to the present invention includes a reference voltage generating unit operated by an input signal and generating a reference voltage in accordance with a power supply voltage, a reference voltage sensing unit determining whether an output signal from the reference voltage generating unit is lower than a predetermined voltage level, and a start-up circuit unit determining an initial operation of the reference voltage generating unit in accordance with a reset signal and supplying the input signal to restart the reference voltage generating unit in accordance with an output signal from the reference voltage sensing unit.
