Abstract:
1. A complementary band-gap voltage reference circuit comprising: first and second groups of transistors, wherein emitter-collector paths of a first transistor of each of said first and second groups being connected in parallel from a common connection so as to present differential base-emitter voltages across said first transistors, wherein a second transistor of each of said first and second groups being connected with its emitter-collector path in parallel with a base-emitter junction of said first transistor of the same group so as to present differential base-emitter voltages of said second transistors across said first and second groups of transistors, wherein output terminals connected to receive a regulated voltage which is an additive function of said differential base-emitter voltages and of additive base-emitter voltages of transistors with smaller emitter current conduction area and different type.
