Abstract
A pixel array includes a plurality of pixel cells, each including a photodiode configured to photogenerate image charge in response to the incident light, a first floating diffusion (FD) coupled to receive the image charge from the photodiode, a reset transistor coupled between a voltage source and the first FD, a second FD coupled between the first FD and ground, a first dual FD transistor coupled between the first and second FDs. Second FDs of first and second pixel cells are coupled. Second FDs of third and fourth pixel cells are coupled.
