Photosensitive part and solid-state image pickup device

摘要

A transmission transistor T₂ transfers charges generated in a photodiode PD to a first capacitor part C₁₁ via a first switch SW₁₁, and transfers the charges to a second capacitor part C₁₂ via a second switch SW₁₂. An amplification transistor T₁ outputs a voltage corresponding to the amount of accumulated charges in at least one of a first capacitor part C₁₁ and a second capacitor part C_12, connected to a gate terminal, and a gate terminal of the amplification transistor T₁ is connected to at least one of the first capacitor part C₁₁ and the second capacitor part C₁₂.
