Abstract
An image sensor may include a pixel array and associated readout paths calibration circuitry. The image sensor may include first column readout circuits formed along a first edge of the pixel array and second column readout circuits formed along a second opposing edge of the pixel array. The readout paths calibration circuitry may include one or more first calibration readout circuits located by the first edge of the array, one or more second calibration readout circuits located by the second edge of the array, and an error detection circuit configured to output an error signal based on signals output from the one or more first calibration readout circuits and the one or more second calibration readout circuits. The one or more second calibration readout circuits and the second column readout circuits can receive a reference voltage that is dynamically adjusted based on the error signal.
