Abstract: A fingerprint sensing system comprising a plurality of conductive selection lines; a plurality of conductive read-out lines crossing the selection lines; selection circuitry controllable to provide a selection signal on at least one selected selection line in the plurality of selection lines; a plurality of pixel elements formed at intersections between the selection lines and the read-out lines; current providing circuitry coupled to the read-out lines and controllable to generate a current pulse in at least one of the read-out lines when reading out a sensing signal from each of the pixel elements.
