Abstract

A solid-state imaging device includes: a photoelectric conversion unit which converts light into signal charges; an accumulation unit which accumulates the signal charges; a transfer transistor connected between the photoelectric conversion unit and the accumulation unit for transferring to the accumulation unit, the signal charges obtained through the conversion by the photoelectric conversion unit; an amplification transistor for amplifying the signal charges accumulated in the accumulation unit to generate a voltage signal, the amplification transistor having a gate connected to the accumulation unit; a reset transistor for resetting a voltage of the accumulation unit; a first amplification circuit for negatively feeding back the voltage signal generated by the amplification transistor to the reset transistor; and a second amplification circuit for positively feeding back the voltage signal generated by the amplification transistor to the amplification transistor.
