ABSTRACT:
A current amplifier (CMA) having plurality of input terminals and an output terminal. Each input circuit and the output circuit of the CMA includes the conduction path of a separate one of a plurality of transistors. Means are provided for applying substantially the same potential to the control electrode of each of these transistors, which means includes an input-terminal-to-control-electrode degenerative feedback connection for each of the transistors having its conduction path in an input circuit. By including a unilaterally conductive device in such an input-terminal-to-control-electrode feedback connection, saturation of the transistor associated therewith caused by certain input current conditions is forestalled.
