ABSTRACT:
A bandgap reference generator providing a reference voltage V.sub.R from a power supply voltage V.sub.DD. The bandgap reference generator includes a bandgap reference circuit and a voltage regulation circuit coupled thereto. The voltage regulation circuit operates to supply power to the bandgap reference circuit such that the voltages at a first internal control node and a second internal control node are equal, wherein the first internal control node and the second internal control node are disposed on different current paths within the bandgap reference circuit. By equalizing voltages at these internal control nodes, device stress within the bandgap reference circuit is reduced. Kick-start circuits for the voltage regulation circuit and the bandgap reference circuit are also included within the bandgap reference generator. In addition, output stage processing can be incorporated to transform an outputted reference voltage V.sub.R from a low stress operating point to a desired reference voltage V.sub.REF.
