Abstract:
A shared active pixel sensor includes a first shared photodiode, a first shared sense node, a first transfer gate, a first shared reset gate and a first shared source follower gate. The first shared photodiode consists of a first signal node and a second signal node. The first shared sense node is electrically connected to the first shared photodiode. The first transfer gate is disposed between the first signal node and the first shared sense node so that the first signal node and the first shared sense node together serve as a source and a drain controlled by the first transfer gate. The first shared reset gate is electrically connected to the first shared sense node. The first shared source follower gate is capable of reading a photocurrent from the first shared photodiode.
