ABSTRACT:
A voltage reference generator circuit (600) that operates at low voltages may be obtained by using a summation circuit (618) to combine a divided bipolar junction voltage signal (616) and a multiplied voltage signal (622) that is proportional to absolute temperature. The voltage reference generator circuit (600) generates a voltage reference which is divided by a divide circuit (620) which produces the divided signal (616), and a voltage reference which is multiplied by a multiply circuit (630) which produces the multiplied signal (622). In another form, a bipolar junction voltage and a voltage that is proportional to absolute temperature may be converted to currents and summed to provide a current which is converted into the reference voltage output.
