ABSTRACT:
A circuit and method for starting up a band-gap reference circuit. In one example, a startup circuit compares a Vbg voltage output of a band-gap reference circuit to a voltage (such as Vbe) across a transistor in order to selectively control whether to inject current into the band-gap reference circuit during startup.
