Abstract
An image sensor includes a pixel array that includes a plurality of pixels, and a row driver. Each pixel includes a photodiode, a transfer gate transistor between the photodiode and a floating diffusion node, and a first transistor between the floating diffusion node and a first voltage node configured to receive a first voltage. The row driver is connected with rows of the pixels through row lines. For each pixel of a selected row among the rows, the row driver is configured to apply a second voltage to a gate of the first transistor such that the first transistor is turned on and the floating diffusion node is reset, and turn on the transfer gate transistor such that electrons integrated in the photodiode are dumped to the floating diffusion node.
