Abstract
An electronic device includes a reference resistor, two first terminals between which the reference resistor is connected, and two second terminals between which a modified impedance value of the reference resistor is intended to be obtained. The electronic device also includes a first circuit that applies between the two second terminals a voltage substantially equal to that between the two first terminals, and a second circuit that flows between the two second terminals a second current the value of which corresponds to a fraction of a first current for flowing in the reference resistor between the two first terminals.
