Abstract
A novel digital calibration scheme is developed to improve the linearity of a wide dynamic range (DR) CMOS imaging sensor, with a low calibration overhead. Experimental results show that the distortion of the fabricated imaging sensor reaches -75.6-dB over the 95.3-dB DR after calibration.
