Abstract
A correlated double sampling pixel gain amplifier includes an operational amplifier, an input sampling capacitor, and a feedback capacitor. The input capacitor samples the input signal during a first time phase and the feedback capacitor receives the signal charge from the input capacitor. No sampling switch is located between the input capacitor and the input terminal. The feedback capacitor may include a capacitor array.
