Abstract:
An image sensor includes a plurality of pixel cells organized into rows and columns of a pixel array. A bit line is coupled to each of the pixel cells within a line of the pixel array. Readout circuitry is coupled to the bit line to readout the image data from the pixel cells within the line. The readout circuitry includes a line amplifier coupled to the bit line to amplify the image data and first and second sample and convert circuits coupled in parallel to an output of the line amplifier to reciprocally and contemporaneously sample the image data and convert the image data from analog values to digital values.
