Summary:The invention provides a power-supply-noise cancelling circuit and a solid-state imaging device. A reference voltage generation circuit generates a reference voltage and outputs it to an amplifier reference voltage line. A power-supply-noise adding circuit adds power supply noise superimposed on a power supply to the reference voltage generated by the reference voltage generation circuit. A differential amplifier amplifies a difference between a voltage of a vertical signal line and a voltage of an amplifier reference voltage line and outputs the amplified voltage.
