Abstract
A complementary metal oxide semiconductor (CMOS) image sensor includes a photodiode, a switch and a comparator. The switch transfers a sensing signal to a sensing node from the photodiode. The comparator, which is directly connected to the sensing node, compares the sensing signal of the sensing node with a reference signal. The comparator outputs a signal corresponding to a voltage difference between the sensing signal and the reference signal.
