Zusammenfassung:An image sensor includes a photodiode disposed in a semiconductor material to generate image charge in response to incident light, and a first transfer gate is coupled to the photodiode to extract image charge from the photodiode in response to a first transfer signal. A first storage gate is coupled to the first transfer gate to receive the image charge from the first transfer gate, and a first output gate is coupled to the first storage gate to receive the image charge from the first storage gate. A first capacitor is coupled to the first output gate to store the image charge.
