摘要： A readout method for reading a sensor includes a matrix of pixels sensitive to a physical phenomenon and delivering an electrical signal the level of which depends on the intensity of the physical phenomenon, the pixels being organized into rows and being connected, via conductors, to readout circuits of the sensor, the readout circuits each comprising an analogue-to-digital converter receiving the electrical signal and delivering digital information depending on the electrical signal. The method comprises the following phases for the readout of each pixel: the matrix of pixels acquiring electric charges; and reading the matrix by transferring the charges acquired during the acquisition phase to the readout circuits, wherein, during the readout phase, multiple successive analogue-to-digital conversions of the acquired charges are carried out in parallel with one and the same acquisition phase. A readout device comprising the readout circuits of the sensor and configured to implement the readout method.

摘要： A digital detector includes a planar sensor and a first monolithic substrate and a second monolithic substrate, the planar sensor being positioned on the first monolithic substrate, the detector comprising, on the first monolithic substrate: a set of pixels organized into a matrix array along rows and down columns and configured so as to generate charges on the basis of radiation; b. column conductors, each connecting the pixels of one same column and intended to carry the charges generated by the pixels; on the second monolithic substrate: c. for each of the column conductors, a charge preamplifier connected to the column conductor, forming a preamplified column conductor that is intended to integrate the charges carried by said column conductor; d. at least one analogue-to-digital converter connected in series to the preamplified column conductors, intended to convert the integrated charges at the output of the charge preamplifiers into a digital voltage; e. a serializer block connected to the at least one analogue-to-digital converter, intended to generate an output voltage.

摘要： A matrix-array detector and to a method for implementing the detector are provided. The detector includes an array of pixels that are sensitive to a physical effect and arranged in a matrix along rows and down columns, each pixel generating a signal according to the physical effect; row conductors, each allowing the pixels of one row to be driven; a first group of driver modules each delivering selection signals to one row conductor of a first group of row conductors; a second group of driver modules each delivering selection signals to one row conductor of a first group of row conductors; the first and second groups of row conductors being interlaced.

摘要： 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.
