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.

摘要： An analog-to-digital converter (ADC) includes first and second circuits, a differential amplifier, a comparator and a digital-to-analog converter (DAC). The first circuit samples a reset voltage, amplifies the sampled reset voltage, and subtracts a first reference voltage from the amplified reset voltage to produce a first difference. The second circuit samples a signal voltage, amplifies the sampled signal voltage, and subtracts a second reference voltage from the amplified signal voltage to produce a second difference. The differential amplifier produces a third difference based a comparison of the first and second differences from the first and second circuits. The comparator compares an output of the differential amplifier with at least one predetermined comparison voltage and outputs a comparison result as a digital value. The DAC is connected to the first and second circuits and the comparator, and controls the first and second reference voltages in response to the digital value.
