A 256x256 CMOS active pixel sensor (APS) is described for an automotive stereo-vision system. Illumination may vary over several orders of magnitude, requiring a high dynamic range imager. Dynamic range is increased 20/spl times/ using a special clocking scheme for the lateral overflow gate. This dynamic range enhancement offers improvements over(More)
—Oversampled Analog-to-Digital conversion has been demonstrated to be an effective technique for high resolution analog-to-digital (A/D) conversion that is tolerant to process imperfections. The area and power budget of conventionally designed oversampled analog-to-digital converters has precluded their application from areas where a large number of low(More)
