Abstract:
A bandgap voltage reference circuit includes a bandgap voltage generation circuit that can produce a bandgap reference voltage in response to an activation voltage signal, a start-up circuit that can produce the activation voltage signal in response to one-shot voltage pulse and an one-shot pulse generator circuit configured to produce the one-shot voltage pulse. The start-up circuit can be automatically shut off after the one-shot voltage pulse.
