ABSTRACT:
A disclosed reference-voltage generating circuit includes a supply voltage adjusting circuit for adjusting an external supply voltage Vcc and outputting predetermined constant voltages VA and VB; a first voltage supply circuit for generating a voltage Vpn that has a negative temperature coefficient by using the voltage VA; and a second voltage supply circuit for generating a voltage Vptat that has a positive temperature coefficient by using the voltage VB, and for generating the reference voltage Vref, which does not have a temperature coefficient, by adding Vpn and Vptat and thereby canceling the temperature coefficients.
