Abstract
A voltage reference circuit included in a computer system includes two bipolar devices with two different current densities which are used to generate two base-emitter voltages, which are scaled using divider circuits. The voltage reference circuit also includes a feedback circuit that generates a reference voltage using the scaled base-emitter voltages and a feedback signal. The feedback signal is generated using the reference signal and combined with one of the scaled base-emitter voltages to compensate for variations in load current from the reference circuit.
