Abstract:
A current-driven pixel circuit and a related image sensor are disclosed. The image sensor includes a pixel circuit array and a current reference circuit. The pixel circuit array includes a plurality of pixel circuits, each having a photo detecting element and a power element. The photo detecting element changes impendence in response to illumination. The power element is arranged to selectively provide a driving current to the photo detecting element. The current reference circuit includes a current source, wherein the power element provides the driving current according to a reference current of the current source, respectively.
