ABSTRACT:
A charge transfer device for a linear photosensor is disclosed. It is necessary to provide for anti-dazzle devices to prevent charges, generated in excessive quantity by the photosensor, from saturating the read shift register. To prevent excess charges from being introduced into the register during the transfer between a storage gate and the register, and to enable a juxtaposition, with a small pitch, of the read elements of each photodiode of the reading device, a structure is proposed with an input diode De, and on a first side of the diode, an input gate, a storage gate and the gate for transfer to the shift register; these three elements are standard ones; on the other side, three successive gates, the first one being adjacent to a charge removal region. The potential imposed on the first of these three gates is greater than the potential imposed on the input gate of the other side of the diode.
