Abstract
An image sensor device may include an array of image sensing pixels arranged in rows and columns. Each image sensing pixel may include an image sensing photodiode, a first source follower transistor coupled to the image sensing photodiode, and a switch coupled to the image sensing photodiode. Each image sensor device may include a second source follower transistor coupled to the switch, and a row selection transistor coupled to the first and second source follower transistors.
