摘要： In a floating diffusion output type or a floating gate output type charge-to-voltage converter, the floating diffusion or the floating gate is coupled to one or more diffusion regions by means of one or more switch elements, and such elements are selectively turned on or off in such a manner that the the charge-to-voltage conversion factor is raised to obtain a great voltage amplitude when a small quantity of signal charge is input, or the conversion factor is lowered to obtain a small voltage amplitude when a large quantity of signal charge is input.
