  • Image sensor
    Patent number: 9749560
    Abstract: An image sensor may include a pixel array in which a plurality of pixel units are arranged in a matrix structure. Each of the pixel units may include a light receiver suitable for generating photocharge in response to incident light, a floating diffusion node electrically coupled to an end of the light receiver, and a reset transistor electrically isolated from the floating diffusion node, wherein a floating diffusion node of a first pixel unit among the plurality of pixel units is electrically coupled to a reset transistor of a second pixel unit adjacent to the first pixel unit among the plurality of pixel units.
