Abstract:
1. A solid-state image pickup device comprising: a pixel; an amplifier unit configured to amplify a signal output from the pixel; a current supplying unit configured to selectively supply a first current and a second current smaller than the first current to the amplifier unit; a holding unit configured to hold a signal output from the amplifier unit; an NMOS transistor having one main electrode electrically connected to an output of the amplifier unit and another main electrode electrically connected to the holding unit; and a voltage supply unit configured to supply an electric potential to the one main electrode of the NMOS transistor; wherein, in a period where the current supplying unit supplies the second current to the amplifier unit, the voltage supply unit supplies an electric potential such that a difference between an electric potential of a control electrode of the NMOS transistor and the electric potential of the one main electrode is negative.
