1. An electronic inductor circuit comprising:

  • an input node connected to a telephone line;

    a ground node;

    a first transistor device having a first terminal connected to the input node, a second terminal and a third terminal;

    a second transistor device having a first terminal connected to the third terminal of the first transistor device, a second terminal and a third terminal;

    a resistor connected between the third terminal of the second transistor device and the ground node;

    a resistor biasing network connected between the input node and the ground node and to the second terminal of the first and second transistor devices for electrically biasing the transistor devices; and

    a capacitor connected between the second terminal of the first transistor device and the ground node.
