Abstract
One imaging apparatus includes a first amplifier circuit, a second amplifier circuit, and a limiter circuit that limits the output of the first amplifier circuit, and further includes a configuration to clamp the output of the limiter circuit. Moreover, another imaging apparatus includes a fully differential amplifier circuit that outputs an amplified noise signal amplified from a noise signal, and an amplified optical signal amplified from an optical signal, and an output limiting circuit that limits each of the amplitude range of the amplified noise signal and the amplitude range the amplified optical signal.
