ABSTRACT:
A pair of transistors have interconnected emitters connected to a constant-current supply which determines the combined values of their emitter currents--and thus of their collector currents. The ratio between their collector currents is controlled by the temperature at which they and an auxiliary forward-biased semiconductor junction are operated, the base electrodes being differentially biased by a fraction of the potential developed across the auxiliary semiconductor junction.
