Abstract
In a pixel signal processing part, a first input switch and an output switch are turned on and off in phase. When the first input switch and the output switch are ON and the second input switch is OFF, a first auto-zero switch and a second auto-zero switch are kept in the ON state to connect the second node to the reference potential (GND), so that a sampling capacitor, a feedback capacitor, and an auto-zero capacitor are operated in respective operation ranges of the capacitors, and the feedback capacitor is kept constant according to a difference of the input pixel signals, thereby making the output of the amplifier in linear response to the input signal.
