This device finds interesting applications in the field of interface circuits for optical fibers. There is proposed in this circuit to utilize a symmetrical amplifier (19) to which an automatic gain control circuit (27) is added which is insensitive to variations of the offset voltage of this amplifier. This control circuit (27) comprises peak detectors which give the best results in a circuit of this type intended for processing signals at very high frequencies.
