A circuit arrangement for reproducing in an output circuit (4) a current (i1) flowing in an input circuit (1) comprises a PNP-current mirror (2) to the input (2-1) of which the input circuit (1) is connected. The mirror output (2--2) is connected to the emitter of an output transistor (3) of the PNP-type the collector of which is connected to the output circuit (4). The base of the transistor (3) is connected to the input (5-1) of an NPN-current mirror (5), whose output (5-2) is connected to the input (2-1) of the PNP-current mirror (2), so that the effect of the base current (ib) of the transistor on its collector current will be compensated for.
