More Information
Summary:Photodetector 1 is equipped with photodiodes PDn, integrating circuits 10 n, CDS circuits 20 n, and hold circuits 30 n. Each integrating circuit 10 n includes an amplifier 11 n, a capacitor C, and a switch SW. Photodiodes PDn are aligned on a first substrate 100 . A differential pair input part (transistors T1 and T2) of amplifier 11 n, capacitor C, etc., of each integrating circuit 10 n are disposed on a second substrate 200 . A drive part (transistors T5 and T6) of amplifier 11 n, etc., of each integrating circuit 10 n are disposed on a third substrate 300.
