ABSTRACT:
Two current circuits are between two common terminals (+V.sub.B and -V.sub.B). The ratio between the currents in the two current circuits is defined by a first current-dividing circuit, and the absolute values of these currents are defined by means of a second current-dividing circuit, in particular a resistor in this second current-dividing circuit. In order to ensure that the current-stabilizing assumes the proper state upon activation, a first current-supply circuit is coupled to the input of the second current-dividing circuit, which current-supply circuit comprises the series arrangement of a resistor and a transistor arranged as a diode, and a second current-supply circuit is coupled to the output of the current-dividing circuit, which second current-supply circuit includes a transistor whose base is connected in common with that of the transistor of the first current-supply circuit.
