Abstract
An embodiment of a method for providing a bandgap voltage is described. In such an embodiment, current density of a current in a bandgap circuit is shifted into a current density range having at least a substantially stable scaling factor to enhance temperature stability of the bandgap voltage, and the bandgap voltage output is moved to a target voltage.
