1. A method for adjusting an impedance of a substrate of a Metal-Oxide-Semiconductor transistor, said method comprising:

  • a) providing a bias voltage fixed at a predetermined value;

    b) connecting a frequency-selective circuit between said substrate and said bias voltage;

    c) providing said frequency-selective circuit with at least one reactive element comprising at least one inductive element connected directly between said substrate and said bias voltage, to obtain a predetermined frequency-response of said frequency-selective circuit, thereby adjusting said impedance.
