A voltage generation circuit generates a reference voltage using a bandgap reference. A countering circuit is included to adaptively counter for any deviations caused in a bandgap reference voltage such that the reference voltage is independent of fabrication process variations and changes in ambient temperature. In an embodiment, current, proportionate to deviation in absolute value of Vbe from a nominal value, is injected into an emitter-base junction to cause Vbe to equal the nominal value.
