A band-gap reference voltage generator includes a first reference current generator, a second reference current generator, and a reference voltage generator. The first reference current generator includes: a driver generating a first reference current in response to a first voltage signal generated by comparison of the unique voltage and the thermal voltage. The second reference current generator includes a driver generating a second reference current in response to a second voltage signal generated by comparison of a division voltage of a power-supply voltage and the unique voltage. The reference voltage generator includes a driver forming current mirrors in association with each of the first reference current generator and the second reference current generator, respectively, and generating a third reference current and a fourth reference current via the formed current mirrors, and a current-voltage converter converting the sum of the third reference current and the fourth reference current into a reference voltage, and outputting the reference voltage.
