Abstract

An imaging device including at least one detection element formed of a photodetector associated with and connected to a circuit for reading signals generated by the photodetector. The circuit is provided with an integration stage equipped with an integration capacitor for integrating charges coming from the photodetector, a pulse detection stage for detecting current pulses produced by the photodetector, and a bias stage. The circuit is further provided with an intermediate stage arranged between the bias stage and between respectively the integration stage and the pulse detection stage, the intermediate stage being provided with transistors forming a current mirror and producing on an input branch of the integration stage an image current of a given current delivered by the direct injection transistor, the intermediate stage being configured to convert the given current into a potential on an input node of the pulse detection stage.
