Abstract
An imager with an analog-to-digital converter having at least one ramp generator that precisely and efficiently produces the desired ramp voltages required by the analog-to-digital converter. The analog-to-digital converter can use differential or two ramp generators. The analog-to-digital converter can also use ramp generators operated in linear or compressed ramp modes.
