Abstract
Photo-detector device for electro-optical sensors, comprising at least a detection and conversion circuit, or pixel (), having at least a photo-sensitive reception mean () and a reset control terminal (), which is able to drive an element to control the charge dissipation () of the photo-sensitive reception mean (). The pixel () is able to convert the current generated by the photo-sensitive reception mean () into a voltage signal on a read-out terminal (). The photo-detector device also comprises a circuit for controlling the reset voltage (), able to generate a suitable input signal to the reset control terminal () by connecting it alternatively to a reset terminal () or to an external reference terminal (), the input signal to said external reference terminal () is the type that can be programmed from outside. Furthermore, the circuit for controlling the reset voltage () can be shared between a subset of detection and control circuits ().
