Abstract
A charge transfer device and method are disclosed in which a plurality of signal charges corresponding to one information input signal are injected into a surface region of a semiconductor substrate beneath specific ones of a plurality of transfer gate electrodes corresponding to said signal charges and transferred therethrough by the transfer gate electrodes. Transferred signal charges subsequent to the first signal charge transferred are detected, thereby using residual charges to prevent decrease in the amount of the detected transfer charges and thus allowing the output signal to appear at the output terminal with a minimum of attenuation even if an increased number of transfer gate electrodes are used.
