Paper Abstract

The charge packet transfer rate is one of the most important factors of charge transfer losing (CTL) in Charge Coupled Devices (CCD). It is important to build up a model of CCD structure parameters, charge transfer efficiency (CTE), transfer frequency of charge packet and work temperature etc. But it is very hard to build up an exact theoretical model and find the analytical solution neither math nor physics. The traditional discussion of the working principle of CCD build up a nonlinear partial differential equation, but it just consider the remainder electrons concentration while integer k=0. In this paper, we increase the result of the electrons concentration while k=1, 2,..., n, and discuss the result. A more accreted result of the charge packet rate had been got. The result is 81 percent of the CTL which is traditionally discussed about of CCD. Then the CTE in low temperature is discussed using the result. And the optimum frequency of the CCD is corrected also. The correction of the charge packet rate in CCD can enhance the performance of CCD.
