IMAGING DEVICE WITH ZERO OHMIC DROP IN A DATA CONDUCTOR

摘要

The invention relates to an imaging device comprising a matrix of pixels, at least one data conductor (Col_b) that can be connected to several pixels of the matrix, organized row-wise and making it possible to successively convey signals delivered by respectively each of the pixels of the row and an electronic current generator (T4) supplying several pixels, each of the pixels of the matrix comprising: ° a transistor (T2) delivering at one of its terminals, said node of the pixel, the signal delivered by the pixel considered and in which a bias current arising from the current generator (T4) can flow, ° and a first electronic switch (T3b) making it possible to connect the node of the pixel to the data conductor (Col_b) associated with this pixel as a function of a pixel selection signal (Phi_ligne). According to the invention, each of the pixels of the matrix furthermore comprises a second electronic switch (T3a), distinct from the first electronic switch (T3b), linked to the node of the pixel and enabling the current arising from the generator (T4) to flow in the transistor as a function of the pixel selection signal (Phi_ligne).
