US Patent 7116366 CMOS aps pixel sensor dynamic range increase

An image sensing device, such as a CMOS Active Pixel Sensor device, including an array of pixels. Each pixel has a photoreceptor, a follower transistor connected to the photoreceptor, a select transistor connected to the follower transistor, and a reset transistor. A first bias line provides power to at least a first of the transistors for a first pixel, and a second bias line provides power to at least a second of the transistors of said first pixel different than the first transistor of the first pixel.
