Abstract
A bandgap reference circuit includes at least one transistor, an amplifier and a start-up circuit. The amplifier is coupled to the transistor(s) to establish a bandgap reference voltage. The start-up circuit, in response to the bandgap reference circuit powering up, isolates an output terminal of the amplifier from at least one input terminal of the amplifier and supplies power to the transistor(s) via the output terminal.
