Abstract
An image sensor includes a first photoelectric conversion layer that is configured to convert light to a first signal. The image sensor also includes a transfer transistor. The transfer transistor includes a storage node region which stores the first signal. The transfer transistor also includes a transfer gate which transfers the stored first signal, and a floating diffusion region that receives the first signal. The image sensor includes a reset transistor that resets the floating diffusion region, and a drive transistor which receives a pixel voltage. The drive transistor generates an output voltage. The image sensor also includes a selection transistor which outputs the output voltage. A reset drain voltage is applied to a drain electrode of the reset transistor, and is independent of the pixel voltage. The reset drain voltage ranges from about 0.1V to about 1.0V.
