Abstract
An imager may include an array of pixels. The pixel array may be arranged in rows and columns. Each pixel of the pixel array may include a photodiode that is coupled to a floating diffusion region by a transfer gate. A source-follower transistor may be coupled between the floating diffusion region and a pixel output node. The imager may include ramp circuitry that provides a ramp signal to the floating diffusion region. A capacitor interposed between the ramp circuitry and the floating diffusion region may be used in conveying the ramp signal to the floating diffusion region. The pixel may be coupled to a comparator that is implemented using separate circuitry or may include portions of the pixel.
