摘要： The present invention provides a dual conversion gain image sensor comprising: a pixel circuit, through which pixel power supply voltage noise is transferred to a bit line; a power supply noise cancellation circuit with an input to which the pixel power supply voltage is applied, the power supply noise cancellation circuit mimicly producing a first transfer function with the aid of a low conversion gain path, the power supply noise cancellation circuit mimicly producing a second transfer function with the aid of a high conversion gain path; and a comparator. According to the present invention, the low and high conversion gain paths are two independent power supply noise cancellation paths that result in different transfer functions capable of tracking the variation of the pixel power supply voltage in low and high conversion gain modes.

摘要： An electronic device includes an image sensor that generates image data, and an image processor that processes the image data. The image sensor includes a pixel array including pixels repeatedly disposed along a row direction and a column direction. Each of pixels belonging to a first row of rows of the pixel array includes sub-pixels each connected to one of a first transmission metal line, a second transmission metal line, and a third transmission metal line. In response to signals respectively applied to the first to third transmission metal lines, at least a part of charges integrated at the sub-pixels of the pixels belonging to the first row from among the pixels is diffused to corresponding floating diffusion areas.
