Claim 5:
6. The solid-state imaging device according to claim 1, wherein the reference voltage generation circuit further includes:
a second operational amplifier that amplifies the predetermined voltage at a predetermined magnification and outputs the reference voltage;
a second capacitive element having one end connected to an input end of the second operational amplifier, the input end being different from an input end to which the predetermined voltage is input;
a third switching circuit that switches a connection destination of the other end of the second capacitive element to either an output end of the voltage generation circuit from which the predetermined voltage is output or a feedback loop of the second operational amplifier; and
a fourth switching circuit that switches whether or not the one end of the second capacitive element is connected to the feedback loop of the second operational amplifier.
