Abstract
A photo-sensitive element for electro-optical sensors, includes a photo-sensitive reception member, a current conversion circuit to convert the current generated by the photo-sensitive reception member into a voltage signal, and an amplification and reading circuit. The current conversion circuit includes a P-channel transistor used as an ideal key and piloted with a voltage that can vary between a high feed voltage and a low feed voltage. The photo-sensitive element is taken to a reset state if the pilot voltage of the transistor is low, and to an integration state if the pilot voltage is high.
