A bandgap voltage reference circuit that utilize a two-stage transconductance amplifier as a feedback control loop to improve the accuracy and stability of the output reference voltage without the need for an additional biasing circuit. The high gain provides a good power-supply rejection ratio, and improves the circuit performance. The amplifier does not require a biasing circuit, thus saving valuable chip space. Furthermore, eliminating the need for a biasing circuit reduces the power consumption of the circuit.
