Abstract
A photosensitive sensor includes multiple elementary sensors butted together, each elementary sensor comprising a pixel matrix organized in rows, the pixels of each row being connected to conductors of multiple types, column conductors of which are connected to read circuits of the sensor. The sensor moreover comprises, connected to each of the column conductors, a group of components that is separate from the conductor under consideration, the group of components forming a matching impedance of the conductor under consideration. The impedances in each elementary sensor have the same value and the impedances for different elementary sensors have different impedance values so as to balance the link impedances between the various read circuits and the corresponding column conductors for the various elementary sensors.
