Abstract

The invention relates to a device for transitioning a bandgap reference circuit to its operational mode, of supplying a reference voltage, when power is supplied to the combined circuits. The device is comprised of a supply-independent biasing circuit that is electrically connected to a start-up circuit and supports the start-up circuit's ability to cause a bandgap reference circuit to transition to its operational mode for any supply voltage that supports the bandgap reference circuit's operational mode.
