Dual pinned diode pixel with shutter
Abstract:
A pixel having an electronic shutter suitable for use in a pixel array of an imaging device includes a pinned diode and a shutter transistor. The pinned diode is utilized as a storage device while the shutter transistor controls charge transfer from the electronic shutter. The use of a pinned diode as a charge storage device for the electronic shutter permits greater charge transfer efficiency, has lower leakage (or “dark” current), and permits the resulting pixel to have a greater fill factor than pixels utilizing conventional electronic shutter circuits.
