摘要： A sensing device includes a pixel unit and an output unit. The pixel unit includes a sensing element, a transfer transistor, a reset transistor, and an output transistor. The transfer transistor is coupled between the sensing element and a floating diffusion node. The reset transistor is coupled between a first node and the floating diffusion node.

During a readout period, the reset transistor is controlled by a reset phase to reset a level of the floating diffusion node. The output unit generates a pixel output signal at the first node according to the level of the floating diffusion node and a reference signal. During the readout period, the reference signal is at a higher level, and after the reset phase, the reference signal is at a lower level.

摘要： A binning circuit and method for an image sensor is disclosed. A column amplifier (CA) is first reset, and thus generates a CA reset signal. A capacitor and a switch network are coupled between an output of the image sensor and an input of the column amplifier. A correlated double sampling (CDS) circuit controllably receives the output of the column amplifier. The switch network is controlled in a way such that an image signal of a first group of the image sensor is transmitted and stored in the CDS circuit, and an image signal of a second group is then added to the stored image signal of the first group.
