ABSTRACT:
A voltage regulator circuit comprises an amplifier, bias network and startup circuit. The bias network is configured to generate a bias voltage for setting a bias current in the amplifier. The startup circuit is configured to mirror the amplifier bias current and to assist the bias network in setting the amplifier bias current based on the mirrored amplifier bias current until the bias voltage approximates a desired level.
