ABSTRACT:
A device for supplying a regulated current to an integrated circuit with current injectors. This device comprises two current paths, the currents which flow in the current paths having a fixed ratio which is maintained by means of a current dividing circuit and upon which current a current dependent ratio is imposed by means of a coupling circuit, in order to stabilize two currents. In accordance with the invention at least one of the semiconductor junctions included in the device, which also stabilize the currents, is constituted by the circuit to be powered, which is based on the recognition that the circuit to be powered exhibits a voltage-current characteristic which corresponds to that of a forward-biased semiconductor junction.
