ABSTRACT:
A reference voltage generator uses a conventional forward junction voltage generating device and a conventional thermal generator to generate a thermal voltage. The forward junction voltage and the thermal voltages have respective thermal sensitivities that act oppositely to each other so that, when the forward junction voltage is combined with the thermal voltage to produce a reference voltage, the reference voltage is substantially insensitive to temperature. The forward junction voltage and the thermal voltage are combined to produce the reference voltage in a manner that avoids generating any voltage having a magnitude that is greater than the magnitude of the sum of the forward voltage and the thermal voltage.
