Abstract
A technique for providing a start-up circuit for a bandgap reference. An amplifier configured in a differential arrangement as the bandgap reference. A start-up circuitry ensures that a second input node is maintained at a lower voltage than a first input node of the amplifier at start-up, when the output node corresponding to the second input side of the amplifier is also pulled low.
