ABSTRACT:
A bandgap reference voltage generating circuit develops a predetermined reference potential between first and second terminals. A pair of transistors are operated at different emitter current densities to develop a difference between their base-emitter potentials. That difference is applied across a first resistance and is increased and applied across a second resistance. The reference potential comprises the sum of at least the scaled-up potential and the conduction potential of a semiconductor junction. A regulating transistor completes a degenerative feedback connection and controls the current flowing between the first and second terminals responsive to the reference potential departing from the predetermined value. A regenerative feedback connection responds to the current in the regulating transistor to decrease the potential across the second resistance when the controlled current increases.
