    Abstract: An image sensor includes first photodiodes sharing a first node that is connected to a first capacitor, second photodiodes sharing a second node that is connected to a second capacitor, a common transistor configured to selectively connect a third node to a pixel voltage node, the third node connected to a third capacitor, a first reset transistor that may selectively connect the first node to the third node, and a second reset transistor that may selectively connect the second node to the third node. The first reset transistor and the second reset transistor may electrically connect the first node, the second node, and the third node to each other according to an operation of the first reset transistor and the second reset transistor. The common transistor is configured to reset the third node to the pixel voltage according to an operation of the common transistor.

    Abstract: An image sensor includes: a pixel array including a plurality of pixels, wherein each of the pixels includes first and second photodiodes, first and second transfer gates, and a plurality of active regions; and a logic circuit. Each of a plurality of pixel groups in the pixel array includes a first pixel and a second pixel. The active regions in each of the first pixel and the second pixel include a first active region and a second active region. The first active region is adjacent to the first transfer gate. The second active region is adjacent to the second transfer gate. In each of the pixel groups, a plurality of source-follower transistors respectively has a gate connected to the first and second active regions of the first pixel and connected to the first and second active regions of the second pixel. The source-follower transistors are in the first pixel.
