摘要： Transistor pixel devices, imagers, and associated methods are provided. In one aspect, a transistor pixel device includes a photodiode coupled to a floating diffusion region (FD), a storage node (SN), and a power supply, wherein the FD is coupled between the photodiode and the power supply. The device also includes a first global transfer transistor coupled between the photodiode and the FD for gating between the photodiode and the FD and a second global transfer transistor coupled between the FD and the SN for gating between the FD and the SN. A global reset select transistor is coupled between the FD and the power supply, wherein an open state of the global reset select transistor prevents accumulation of electrical charge at the photodiodes. A source follower transistor is coupled to the FD and to the power supply, where the source follower is operable to receive electrical signal from the FD.
