Analog to digital converting circuit and an operation method thereof
An analog to digital converting circuit includes a correlated double sampling circuit (CDS) that compares a pixel signal with a ramp signal, and outputs a comparison signal, a timing amplifier that increases an active time of the comparison signal “N” times, and outputs an extended signal, wherein the “N” is a positive integer, and a counter that outputs a digital signal corresponding to the pixel signal in response to the extended signal and a first clock signal.
