Abstract
An image sensor and offset-able reference voltage generator thereof are provided. The image sensor comprises a plurality of pixels, an offset-able reference voltage generator and a pixel sampling circuit. The pixel senses light from an image and generate an image signal. The offset-able reference voltage generator provides a reference voltage having a voltage offset. The pixel sampling circuit is coupled to the pixels and the offset-able reference voltage generator to sample the image signal and generate a pixel signal according to the reference voltage. The voltage offset of the reference voltage is able to compensate for the offset voltage in the process of generating the pixel signals.
