Abstract: An image sensing device including a pixel array including a plurality of pixels and an analog-to-digital converter (ADC) configured to convert an analog signal into a digital signal is provided. The ADC includes a first circuit configured to receive the analog signal from a selected pixel among the plurality of pixels and generate a first output signal and a second circuit including a select transistor configured to apply a voltage to a floating node electrically connected to the select transistor based on the first output signal. The second circuit further includes a capacitor connected in parallel between a gate and a drain of the select transistor and an output circuit connected to the floating node and configured to output the digital signal based on the applied voltage to the floating node.

Abstract: An image sensor includes a pixel array in which a plurality of pixels are arranged. Each of the plurality of pixels includes an organic photodiode of which a sensitivity is adjusted based on an external voltage, a silicon photodiode, first and second floating diffusion nodes, a conversion gain transistor, and a driving transistor. Charges generated by the silicon photodiode are accumulated in the first floating diffusion node. Charges generated by the organic photodiode are accumulated in the second floating diffusion node. One end of the conversion gain transistor is connected to the first floating diffusion node and the other end connected is connected to the second floating diffusion node. The driving transistor is configured to generate a pixel signal corresponding to a voltage of the first floating diffusion node.
