ABSTRACT:
A control device for a charge detection circuit comprising a CCD final gate electrode formed on a semiconductor substrate, an electric potential barrier forming gate electrode placed adjacent to the CCD final gate electrode, a diffusion region formed adjacent to the electric potential barrier forming gate electrode, a reset transistor connected to the diffusion region, a source follower circuit which uses as an input an electric potential in the diffusion region, a sample and hold circuit for receiving the output of the source follower circuit at a specified timing, a reference voltage source which has a value determined by the dynamic range of the source follower circuit, and an integrator which integrates a difference between the output of the sample and hold circuit and the output of the reference voltage source, and applies a value obtained by the integration to the electric potential barrier forming gate electrode.
