Abstract
A three-terminal current amplifier with current-mode feedback to stabilize its current gain to be substantially independent of the common-emitter forward current gains of its component transistors. The feedback connection is made by means of a current splitter which includes a pair of emitter-connected transistors operated at substantially the same absolute temperature, T. These transistors have a potential substantially linearly proportional to T applied between their base electrodes. The current-amplifier output terminal is coupled to the interconnected emitter electrodes of the transistors and the collector electrode of the first transistor is coupled to the current-amplifier input terminal.
