ABSTRACT:
This bistatic signal current driver circuit applies positively controlled drive at both signal current levels to an output open collector driver transistor by way of two substantially identical signal translating networks which track each other and compensate for variations in global base-to-emitter voltage drops, beta factors, and supply voltages. An inverted output is available merely by switching connections internally of the two networks to reverse the phase of the driving currents.
