Abstract:
1. A solid-state imaging device comprising: a first photoelectric conversion portion; a floating diffusion node; a first transfer transistor configured to transfer an electron generated at the first photoelectric conversion portion to the floating diffusion node; an amplifying transistor configured to output a signal based on an amount of charge of the floating diffusion node; a voltage-controlled node; and a voltage control portion configured to control a voltage of the voltage-controlled node, wherein the amplifying transistor is configured to output a first signal in a first state where a voltage of the floating diffusion node is reset, wherein the amplifying transistor is further configured to output a second signal in a second state where the electron is transferred to the floating diffusion node, wherein the voltage-controlled node is different from a node to which a voltage configured to set a conductive state of the first transfer transistor is supplied, wherein the voltage-controlled node is coupled to the floating diffusion node via a coupling capacitance, wherein the voltage control portion is configured to control the voltage of the voltage-controlled node so that: wherein the second voltage is higher than each of the first voltage and the third voltage.
