ABSTRACT:
A method of driving a charge detection circuit of floating diffusion amplifier type including, a second conductivity type diffusion region produced on a first conductivity type semiconductor substrate or layer, a voltage barrier gate electrode adjacent the diffusion region, a CCD final gate electrode adjacent the voltage barrier production gate electrode, an MOS transistor for resetting the diffusion region incorporating the diffusion region as a source electrode, a source follower circuit for receiving the voltage of the diffusion region as an input signal. When the signal charges are transferred to the voltage well below the CCD final gate electrode, only the charges exceeding a voltage barrier below the voltage barrier gate electrode are output to the diffusion region.
