Abstract
A capacitive high voltage generator having a first stage and a second stage respectively formed by a first basic block and a second basic block and a third basic block. Each basic block has a timing input, a first supply input, a second supply input and an output terminal and includes: a buffer having a first terminal connected to the first supply input of the corresponding basic block, a second terminal connected to a ground terminal and an input terminal connected to the timing input of the corresponding basic block; a capacitor having a first terminal connected to an output terminal of the corresponding buffer and a second terminal connected, in a non-disconnectable way, to the output terminal of the corresponding basic block; a diode having a first terminal connected to the second supply input and a second terminal connected, in a non-disconnectable way, to the output terminal of the corresponding basic block. The output terminals of the first and second basic blocks are respectively connected to the first supply input and to the second supply input of the third basic block.
