Abstract
A solid-state imaging device includes a pixel including a photoelectric conversion element, an accumulation unit accumulating charges generated by the photoelectric conversion element, a reset unit resetting the accumulation unit at a voltage of equal to or more than 4.05 V, and an amplifier transistor amplifying and outputting a signal corresponding to amount of accumulated charges, a vertical output line connected to the pixel, a current source circuit including first to third transistors flowing a constant current through the vertical output line, and a voltage setting circuit respectively setting the gate voltages of the first to third transistors to a first voltage, a second voltage higher than the first voltage, and a third voltage higher than the second voltage and lower than the power supply voltage so as to set the drain-source voltage of each of the first to third transistors to equal to or less than 1.75 V.
