Abstract
A ramp signal generation device includes a sampling circuit suitable for sampling a ramp current, which flows on a plurality of ramp current paths, and storing a voltage corresponding to the sampled ramp current; a current maintaining circuit suitable for maintaining the ramp current; a current maintaining/transferring circuit suitable for maintaining and transferring a current corresponding to the voltage stored by the sampling circuit; a selection circuit suitable for selecting a ramp current path of the sampling block and the current maintaining/transferring circuit; and a current-to-voltage converter suitable for converting the current transferred from the current maintaining/transferring circuit and generating therefrom a ramp voltage.
