<p>PROBLEM TO BE SOLVED: To provide a driving method of a multipole electric field electron emitting device whose input resistance is large, transfer characteristic is linear, and which is suited for application of a power amplifier or the like of having a large mutual conductance, and having a less gate invalid current. SOLUTION: This has at least a cathode electrode to discharge electrons by an electric field effect, a gate electrode to apply an electric field to the cathode electrode, an anode electrode to which discharged electrons are made to be collected, and a control electrode installed between the cathode electrode and the anode electrode and controlled of the discharged electrons, and the gate electrode is grounded, a cathode voltage of a negative electric potential is applied to the cathode electrode, an anode voltage of a positive electric potential is applied to the anode electrode, and an input signal voltage is applied to the control electrode to control an anode current.</p> |
