ABSTRACT:
This relates to a method of generating at least first and second matched currents from first and second multiple collector transistors. The first transistor has a base region, a first emitter region and a plurality of collector regions. The second transistor has a second emitter region disposed in the base region and also has a plurality of collector regions. Matched currents are taken one each from a collector of the first and second transistors, which collectors occupy corresponding position with respect to their associated emitter regions.
