Abstract
A band gap reference voltage circuit of the present invention includes a first band gap reference voltage formation portion for outputting a first reference voltage and a second band gap reference voltage formation portion for outputting a second reference voltage. The band gap reference voltage circuit then outputs a higher one of the first and second band gap reference voltage formation portions to output a constant reference voltage. Accordingly, even if one of the output voltages decreases caused by applying any stress for the first and second band gap reference voltage formation portions, the higher voltage is output as an output voltage of the band gap reference voltage circuit.
