ABSTRACT:
A supply-voltage detecting stage (11) that supplies first and second reference currents (I.sub.REFP and I.sub.REFN) which vary with the supply voltage (V.sub.cc) and are coupled by first and second gain stages (12A and 12B), respectively, to first and second temperature-detecting stages (13A and 13B), respectively. First and second temperature-detecting stages (13A and 13B) increase the coupled reference currents (I.sub.REFP and I.sub.REFN), respectively, to compensate for temperature increase through use temperature-sensitive, long-channel transistors (M34-M37 and M42-M45), supplying temperature and supply-voltage compensated output bias voltages at output terminals (MIRN and MIRP).
