ABSTRACT:
A voltage-current converter having a balanced-voltage input and a balanced-current output. Each of the emitter circuits of the two input transistors includes a three-transistor current-mirror circuit, whose input circuit carries a constant current, whose output circuit carries the balanced-output current and of which the base-emitter junction of the transistor which is included in the input circuit is bridged by a semiconductor junction in the output circuit. The two current mirror circuits are coupled in that a resistor is included between the bases of the transistors which are included in the input circuits of the two current mirror circuits.
