Abstract
A temperature stabilized voltage reference is generated based on the difference in the base to emitter voltages of a pair of transistors operating at different current densities which is summed with a voltage that is a predetermined fraction of one of the base emitter voltages. This voltage is utilized to provide for a constant current through a load by adjusting the current through a sense resistor to the value of the temperature stabilized voltage.
