Abstract
An active pixel sensor is provided. The active pixel sensor includes a substrate, a plurality of sensing circuits, and a plurality of output circuits. The substrate is divided into a plurality of pixel rows. A plurality of pixel areas are disposed on the plurality of pixel rows. The plurality of sensing circuits are disposed in the pixel areas on the pixel rows excluding a specific pixel row among the plurality of pixel rows. The plurality of sensing circuits are further disposed on a plurality of pixel columns to form an array. Each of the plurality of sensing circuits includes a sensing element, a transfer transistor, and a floating diffusion node. The plurality of output circuits are disposed in the pixel areas on the specific pixel row. The sensing circuits on the same pixel column are coupled to the same output circuit.
