Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A solid-state imaging device comprising:
a conversion circuit connected to a vertical signal line extending from a pixel array unit;
a voltage generation circuit that outputs a predetermined voltage; and
a reference voltage generation circuit that receives the predetermined voltage as an input and outputs a reference voltage of the conversion circuit,
wherein the reference voltage generation circuit includes:
an operational amplifier that amplifies the predetermined voltage at a predetermined magnification and outputs the reference voltage;
a 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 first switching circuit that switches a connection destination of the other end of the 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 operational amplifier; and
a second switching circuit that switches whether or not the one end of the capacitive element is connected to the feedback loop of the operational amplifier.
