Abstract
A voltage reference circuit included in a computer system includes an asymmetric differential amplifier circuit that includes two metal-oxide semiconductor (MOS) transistors with different threshold voltages and different current densities. The voltage reference circuit also includes a driver circuit that generates, using a control signal, an output current that is used by a divider circuit to generate a reference voltage and a feedback voltage. The reference voltage and the feedback voltage are used by the asymmetric differential amplifier circuit to generate the control signal.
