ABSTRACT:
A device for generating a voltage comprises first and second plates spaced apart from each other, for being charged at respective different potentials. A third plate is placed at a first distance from the first plate so as to form a first capacitor, and a first semiconductor element is connected between the third plate and the second plate. This voltage generating device produces an output voltage having an amplitude that is dependent upon the first distance and taken between the third and second plates.
