摘要:
A CMOS image sensor includes a photodiode, a switch configured to transfer a signal sensed by the photodiode to a sensing node, and a comparator electrically and directly connected to the sensing node and configured to compare the sensed signal of the sensing node and a ramp signal. Reset offset of the comparator is maintained at a constant offset voltage level during an initialization mode.
