Claim 7:
8. The solid-state imaging device according to claim 1, wherein the reference voltage generation circuit further includes:
a second capacitive element having one end connected to an input end of the 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 second feedback loop of the operational amplifier;
a fourth switching circuit that switches whether or not the second feedback loop of the operational amplifier is connected to the one end of the second capacitive element;
a sample hold circuit that is connected to the feedback loop of the operational amplifier and holds an output of the operational amplifier;
a second sample hold circuit that is connected to the second feedback loop of the operational amplifier and holds an output of the operational amplifier; and
a fifth switching circuit that switches whether or not one of the capacitive element and the second capacitive element is connected to the input end of the operational amplifier.
