Abstract
An image sensing device includes a ramp signal controller configured to generate a bias voltage; a ramp cell array including a plurality of first ramp cells configured to generate a first ramp signal based on the bias voltage and a plurality of second ramp cells configured to generate a second ramp signal based on the bias voltage; and a load resistor array including a plurality of first load resistors connected to the plurality of first ramp cells and a plurality of second load resistors connected to the plurality of second ramp cells. In a first row of the ramp cell array, the plurality of first ramp cells and the plurality of second ramp cells are arranged alternately in a first direction.
