Abstract: In an embodiment, a device for generating a first current from a second current, comprises: an output transistor configured to generate the first current; a first circuit configured to generate a third current representative of the second current and to draw it from a first node; a second circuit configured to generate a fourth current representative of the first current and to supply it to the first node; and a third circuit receiving a fifth current representative of a difference between the third and fourth currents, the third circuit being configured to generate a sixth current representative of the fifth current and to draw it from a control terminal of the output transistor.
