摘要： 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.

The APS array includes a plurality of pixels arranged in a two-dimensional matrix, wherein the APS array generates a reset signal and an image signal for each selected column of the APS array. The first ADC includes a correlated double sampling (CDS) circuit array comprising CDS circuits that are arranged for each column of the APS array, wherein the first ADC generates a digital code from a signal corresponding to the difference between the reset signal and the image signal which are generated by the CDS circuit using a ramp signal. The ramp signal generator generates the ramp signal, wherein a second ADC receives a feedback of the generated ramp signal and generates a feedback reference code, and wherein the ramp signal generator calibrates the ramp signal based on a comparison using the feedback reference code.
