ABSTRACT:
An analog-to-digital converter in an image sensor is implemented with a plurality of comparator units. Each comparator unit has a respective capacitor array and respective switches integrated therein. Such capacitors and switches across the comparator units are operated for generating ramp voltages for such comparator units for performing analog-to-digital conversion with correlated double sampling. Thus, circuit area and power consumption of the CMOS image sensor may be minimized.
