Abstract
An embodiment device includes a first MOS transistor and a first resistor in series between first node and second nodes, the first resistor being connected to the second node; a second MOS transistor and a second resistor in series between the first and second nodes, the second resistor being connected to the second node and the gates of the first and second transistors being coupled to each other; an operational amplifier including a first terminal connected to a node of connection of the first resistor to the first transistor, a second terminal, and an output terminal coupled to the gate of the first transistor; and a circuit configured to supply a set point voltage to the second terminal of the amplifier.
