Claim Text:
1. An apparatus comprising: a ready circuit to output a ready indicator when a supply voltage provided to the ready circuit and a voltage regulator is sufficient to operate the voltage regulator; the voltage regulator to receive the supply voltage and to output a regulated voltage, the voltage regulator to receive a first current from the ready circuit and to control the regulated voltage based on the first current when the ready indicator is inactive; a bias circuit to receive the regulated voltage and including a first circuit to generate a first bandgap bias current and a second circuit to generate a second bias current; and an output circuit to receive a selected one of the first bandgap bias current and the second bias current and output one or more bias outputs to one or more client circuits based on the selected one of the first bandgap bias current and the second bias current.
