A differential current amplifier suitable for realization in monolithic integrated circuit form includes a pair of input transistors supplied with differential current at the bases thereof. The emitters of the transistors are interconnected, as are the collectors, and feedback resistors are connected between the collectors and the bases of the respective transistors. A pair of output transistors have the bases coupled in common with the bases of the input transistors and the emitters connected in common with the emitters of the input transistors, so that the collectors of the output transistors then provide a differential output current in accordance with differential input current supplied to the bases of the input transistors.
