Abstract
A ramp generation circuit including, a charge supply unit which generates predetermined charges every predetermined time, an integration circuit which accumulates the charges generated from the charge supply unit and converts the charges into a voltage, and, an attenuation unit which outputs, to an output terminal, a voltage obtained by attenuating a noise value of an output voltage from the integration circuit.
