Abstract
An image sensor pixel includes a substrate, a photodiode and a pixel circuit in the substrate. The pixel circuit includes a transfer element, which is electrically connected between the photodiode and a floating diffusion node that accumulates electrical charges generated by the photodiode in response to light incident the substrate, and a driving element, which is electrically connected to the floating diffusion node. An output circuit is also provided, which is electrically connected between a column line and the pixel circuit. The output circuit includes a switching element electrically connected to an output terminal of the driving element, a primary capacitor electrically connected to the switching element, a secondary capacitor, which is selectively connected to or disconnected from the switching element based on an on/off switching state of a first enable element, and a first selection element electrically connected between the switching element and the column line.
