The invention provides a bandgap reference voltage generator. In one embodiment, the bandgap reference voltage generator includes a first current generator, a second current generator, and an output voltage generator. The first current generator generates a first current with a positive temperature coefficient. The second current generator generates a second current with a negative temperature coefficient. The output voltage generator generates a third current with a level equal to that of the first current, generates a fourth current with a level equal to that of the second current, adds the third current to the fourth current to obtain a combined current with a zero temperature coefficient, and generates a reference voltage according to the combined current.
