Solid-state imaging devices are disclosed. In one example, a solid-state imaging device includes a conversion circuit connected to a vertical signal line of a pixel array, a voltage generation circuit that outputs a predetermined voltage, and a reference voltage generation circuit that receives the predetermined voltage and outputs a reference voltage. The reference voltage generation circuit includes an operational amplifier that amplifies the predetermined voltage and outputs the reference voltage, a capacitive element having one end connected to an input of the operational amplifier that is different from an input that receives the predetermined voltage, a first switching circuit that connects the other end of the capacitive element to either the predetermined voltage output from the voltage generation circuit or a feedback loop of the operational amplifier, and a second switching circuit that selectively connects the one end of the capacitive element to the feedback loop of the operational amplifier.
