Device comprising a circuit for processing an alternating signal, this circuit including a first stage with a first active element biased by a first bias voltage (VDD) applied between its first main electrode, and its second main electrode, and by a second bias voltage (VG) applied between its control electrode and its second main electrode, this control electrode also receiving the alternating signal, this active element being of the type in which, in operation, normally no bias current flows in the control electrode, characterised in that the second DC bias voltage VG is generated at the terminals of a resistor R coupled to the control electrode and to the second main electrode, by the application, to the control electrode, of an alternating signal with sufficient power to invoke the rectifying properties of the active element between its control electrode and its second main electrode. <IMAGE> |
