Patent abstract
A solid-state image pickup device includes a detection diode for detecting a transfer charge and a switched capacitor amplifier whose input section is connected to the detection diode. The switched capacitor amplifier includes an inverting amplifier, a reset transistor and a feedback capacitor which are connected between input and output sections of the inverting amplifier. Thus, the solid-state image pickup device satisfies the requirements for both improvement in charge-voltage conversion efficiency and reduction in generated noises.
