摘要：A charge transfer device and its driving method are disclosed such that transferpulses each having an amplitude substantially equal to that of transfer pulses applied totransfer electrodes at transfer stages before a plurality of successively-arrangedtransfer stages including a final transfer stage and DC offset levels so decreasedgradually as to gradually make shallow the depth of potential wells formed under thetransfer electrodes toward the final transfer stage are applied to transfer electrodes(16n-2 to 16n; 17n-2 to 17n) at successively-arranged plural transfer stages including thefinal stage. Further, a charge transfer device and its driving method are disclosed suchthat a transfer pulse having an amplitude substantially equal to that of transfer pulsesapplied to transfer electrodes at transfer stages before the final transfer stage and a DCoffset voltage so biased as to allow the depth of potential well formed under thetransfer electrodes at the final transfer stage to be shallower than that of potentialwells formed under the transfer electrodes at the transfer stages before the finaltransfer stage is applied to the transfer electrode at the final transfer stage.
