Patent ID: 11394910

Abstract:
An image sensing device includes a floating diffusion node, a reset circuit coupled between a supply terminal of a high voltage and the floating diffusion node, and suitable for resetting the floating diffusion node with the high voltage during a reference period based on a reset control signal, a photodiode coupled between a supply terminal of a low voltage and a coupling node, and suitable for generating a photocharge based on incident light during an exposure period, a transmission block coupled between the coupling node and the floating diffusion node, and suitable for transmitting the photocharge to the floating diffusion node during a transmission period based on a transmission control signal, and a selection circuit coupled between an input terminal of a boost control signal and an output terminal of a pixel signal, and suitable for generating the pixel signal with a boost voltage greater than the high voltage during the transmission period based on a selection control signal and a voltage applied to the floating diffusion node.
