An electronic device for the production of pulse signals of an amplitude greater than the amplitude of a given periodic signal, said device comprising:

• two supply terminals connectible respectively to a first and second pole of a source of d-c voltage of an amplitude at least equal to the one desired for the said pulse signals, a first of these terminals being a common point of the circuit of the device;
• a first input terminal connectible to a first source of periodic voltage producing signals whose period is submultiple of the duration of each of said pulse signals;
• a second input terminal connectible to a second source of periodic voltage of the same frequency but phase-opposed in relation to the periodic voltage provided by the first periodic voltage source;
• a third input terminal to receive the said periodic signals;
• an output terminal to which the said pulses are supplied:
• a first IGFET charge transistor connected by one of its secondary electrodes to the said output terminal and by its other secondary electrode to the second of the said supply terminals, the control electrode of the first IGFET charge transistor being connected to the said first terminal through a first coupling circuit including at least one condenser connected at one side to the said control electrode of said first charge transistor;
• a second IGFET charge transistor connected by one of its secondary electrodes to the said output terminal and by its other secondary electrode to said second supply terminal, the control electrode of said second IGFET charge transistor being connected to said second input terminal through a second coupling circuit including at least one condenser connected at one side to said control electrode of said second charge transistor;
• first and second IGFET decoupling transistors connected by their respective control electrodes to the said third input terminal and by one of their respective secondary electrodes to the plates of the condensers included respectively in the first and second coupling circuits, the other secondary electrode of each decoupling transistor being connected to a power source for supplying the decoupling transistors;
• first and second further IGFET transistors each connected by one of its respective secondary electrodes to said output terminal, the other secondary electrode of the first further transistor being connected to the control electrode of the first charge transistor, the other secondary electrode of the second further transistor connected to the control electrode of the second charge transistor, the control electrode of the first further transistor being connected to the control electrode of the second charge transistor, the control electrode of the second further transistor being connected to the control electrode of the first charge transistor;
