Abstract

An image sensing device includes a coarse current generation circuit suitable for generating a coarse ramp current adjusted to a coarse level for a single ramp period, a fine current generation circuit suitable for generating a fine ramp current adjusted to a fine level for the single ramp period, and a current-to-voltage conversion circuit suitable for generating a ramp voltage corresponding to a resultant current of the coarse ramp current and the fine ramp current for the single ramp period.
