Abstract
An electron emitting comprising an emitter electrode for emitting electrons when applied with an electric field, a gate electrode for extracting the electrons emitted from the emitter electrode, when applied with a voltage from a signal source, the voltage being positive with respect to the emitter electrode, an anode electrode connected to a load, for collecting the electrons extracted by the gate electrode, and for passing an anode current, and a gate resistor connected between the signal source and the gate electrode, for reducing a gate current flowing in the gate electrode, without changing an anode current flowing in the anode, and for lowering a gate voltage by utilizing a voltage drop cause by the gate current.
