Abstract
In various embodiments, an image sensor and related methods of operation of the image sensor are disclosed. In an embodiment, an image sensor includes at least one pixel. The at least one pixel including a transistor to couple an overflow capacitor to a floating diffusion node. Under a low light condition, photocharge is to be collected in a floating diffusion, but substantially not into an overflow node. Under a high light condition, photocharge is to overflow into the overflow node. Other sensors and related operations are disclosed.
