Abstract
An image sensing device includes a pixel array including a plurality of unit pixels coupled to a plurality of row lines, wherein at least one of the unit pixels includes a photo-diode for generating photo charges corresponding to an incident light and a transfer transistor for transferring the photo charges to a floating diffusion (FD) node in response to a transfer control signal transferred through a corresponding row line; a row control circuit disposed at a first side of the pixel array and suitable for providing, to the respective row lines, the transfer control signal having a voltage level between a first voltage and a second voltage; and a bias compensation circuit disposed at a second side of the pixel array and suitable for driving the transfer control signal to the second voltage during a reset read-out section of each of the row lines.
