Abstract:
A current mirror comprising:an input node for receiving an input current;an output node for providing an output current;first, second and third transistors, each transistor comprising first and second current path terminals and a control terminal, the control terminals of the first and second transistors being connected to each other, the first current path terminal of the first transistor and one of the current path terminals of the second transistor being connected to a power supply, the control terminal of the third transistor being connected to the input node, one of the first and second current path terminals of the third transistor being connected to the output node and the other of the first and second current path terminals of the third transistor being connected to the other of the first and second current path terminals of the second transistor; anda resistive element connected in series between the input node and the second current path terminal of the first transistor, the control terminals of the first and second transistors being connected to a node between the resistive element and the second current path terminal of said first transistor, said resistive element being a transistor of the opposite polarity to the first, second and third transistors.
