ABSTRACT:
A reference generator circuit generates a reference signal for use by a regulator in generating operational power for circuits and devices. A start-up circuit includes a self-biased voltage reference and a differential amplifier configured to generate a start-up signal to induce current flow in response to the voltage independent reference during the start-up phase of the circuit and cease inducing the current flow following the start-up phase of the circuit. The reference signal is generated by receiving a supply voltage and inducing current flow into a node of a bandgap reference circuit during a start-up phase of the bandgap reference circuit and ceasing inducing the current flow following the start-up phase of the bandgap reference circuit.
