Abstract
An image sensor, readout circuitry for an image sensor, and a method of operating readout circuitry are disclosed. Readout circuitry includes an analog-to-digital-converter ('ADC') including input stage circuitry with a first selectable input and a second selectable input. The ADC is coupled to sequentially receive a first reset signal, a second reset signal, a high gain image signal, and a low gain image signal, in that order. The input stage circuitry is configured to select the first selectable input when receiving the first reset signal and the low gain image signal and select the second selectable input when receiving the second reset signal and the high gain image signal.
