摘要： A charge pump including n cells in series, each cell comprising a shift capacitor (Cdi) and a storage capacitor (Cmi), respectively having a shift parasitic capacitor (Cpi) and a storage parasitic capacitor (Cqi). The presence of the parasitic capacitors (Cpi, Cqi) leads to a loss of charge transmitted to the cell. Each cell comprises charge injection means (Cdinji, Cminji) for partially or totally compensating, or even overcompensating, the lost charge quantity. The charge pump may be implemented in silicon-on-insulator technology.

摘要： The particle detection circuit comprises a plurality of basic circuits. Each basic circuit comprises a particle detector element connected to an associated counter and a summing circuit having a first input connected to the output of the counter. Basic circuits, each forming a subpixel, are grouped together by series connection of their summing circuits to form a pixel. The output of the pixel, formed by the output of the summing circuit of a last basic circuit of the pixel, supplies counting signals representative of the number of particles detected by the set of basic circuits of the pixel. Disabling certain basic circuits of the pixel, by selective zero resetting of the first input of their summing circuit, can enable only the particles detected by certain zones of the pixel to be counted.

Each of the pixels of the said matrix is associated with a current limiting device (5), for limiting the current generated by each of the elementary sensors to a maximum called reference current, regardless of the radiation flux received by the pixel concerned.
