Abstract
A reference voltage supply circuit is provided. The reference voltage supply circuit includes a first amplifier for amplifying a first input voltage and a fed back first reference voltage, a second amplifier for amplifying a second input voltage and a fed back second reference voltage, a reference voltage generator for generating the first reference voltage and the second reference voltage according to output signals of the first and second amplifiers and feeding the first and second reference voltages back to the first and second amplifiers, and a glitch remover turned on/off according to an input pulse signal to conduct or cut off current flowing between a power supply terminal and the ground.
