Abstract

PURPOSE:To make it possible to build the titled converter in a single semiconductor substrate in a body by detecting the amount of random electric charge and then by transferring it by varying the gate area of insulating gate type FET. CONSTITUTION:Analog signal is supplied from input terminal 10 to N type diffused layer area 28. This signal is sampled under gate electrode 29 and stored as charge under gate electrode 30. Next, charge is injected under electrodes 32 and 34 of charge separating circuit 13a composed of gate electrodes 31-34. As charge detector 12a judges that the charge has been injected under electrode 32, the charge under electrode 32 is transferred to diffusion area 43a of gate circuit 14a. The charge under electrode 34, on the other hand, is transferred to charge separator 13b having the electrode area one half as large as that of electrodes 31-34. While the charge exists under electrode 38, the charge under electrode 36 is transferred to diffusion area 43b of gate electrode 14b. Charges in areas 34a and 34b are transferred to diffusion areas 44a and 44b and then outputted from terminals 25 and 26 to a charge detecting element.
