ABSTRACT:
A driver circuit in which the output current is limited to a particular value. A very low value resistance in the output stage senses the current and modulates the conduction to a diode-amplifier combination. The combination employs ratioed emitter areas and currents and can respond to potentials at P-N junction contact potential level. The circuit has a dynamic voltage range that extends to within almost the emitter-collector saturation of a single transistor of zero.
