Abstract
An image sensor includes a controller and a plurality of pixel clusters. Each of the pixel clusters includes a plurality of pixels coupled to a reset transistor, a floating diffusion node, a source follower, and a select transistor. Each pixel of a pixel cluster includes a photodiode, and a transfer transistor having a first terminal coupled to the photodiode, a second terminal coupled to the floating diffusion node, and a gate. The controller is configured to apply a transfer control signal to the gate of the transfer transistor in response to a pixel operation, the transfer control signal being one of a positive voltage level, a negative voltage level, and a ground voltage level.
