Abstract: This invention relates to a device for switching and controlling an electron dose emitted by a micro-emitter comprising a sensor module (30) that receives the output current from the micro-emitter and a voltage to adjust the polarization point of the said device, a comparator module that receives a threshold voltage to adjust the quantity of charges to be emitted, a logical module to initialize the electron emission, and to define whether or not the micro-emitter should emit, a control module that generates the voltages necessary for initialization and extinction of the micro-emitter current pulse, means of varying the threshold voltage.
