Abstract:
A comparator may include: a comparison block suitable for comparing a ramp signal and a pixel signal and outputting a comparison signal; and a gain acquisition and noise reduction block suitable for amplifying the comparison signal outputted from the comparison block to acquire a gain and reduce an occurrence of noise.

Claim (Index 10):
An image sensor comprising:\n a pixel array suitable for outputting a pixel signal corresponding to incident light; a row decoder suitable for selecting a pixel in the pixel array for each row line and controlling the selected pixel, according to control of a controller; a ramp signal generator suitable for generating a ramp signal according to control of the controller; a comparison block suitable for comparing the ramp signal applied from the ramp signal generator with pixel signals applied from the pixel array according to control of the controller; a gain acquisition and noise reduction block suitable for amplifying a comparison signal applied from the comparison block to acquire a gain and reduce an occurrence of noise; a counting unit suitable for counting a clock applied from the controller according to each of output signals from the gain acquisition and noise reduction block; a memory unit suitable for storing counting information provided from the counting unit according to control of the controller; the controller suitable for controlling operations of the row decoder, the ramp signal generator, the comparison block, the counting unit, the memory unit, and a column readout circuit; and the column readout circuit suitable for outputting data of the memory unit according to control of the controller, wherein the gain acquisition and noise reduction block is suitable for receiving a voltage change of the comparison block as a current gain, amplifying the voltage change to acquiring an additional gain, and reducing an occurrence of banding noise and kick-back noise.
