Paper Abstract

High-speed driving signals will easily incur the substrate bounce of CCD(charge-coupled device), causing the charge transfer of CCD, which not only reduces the charge transfer efficiency but also produces dispersion. Thus the CCD imaging quality will be severely influenced. This paper introduces the classification and work principle of driving signals and elaborates the mechanism of the occurrence of the substrate bounce of CCD. Taking the characteristics of high speed driving signals into consideration, the paper provides a method to restrict the substrate bounce's disturbance to CCD signals based on the driving signal wave-shaping theory. Theoretically speaking, the driving signal wave-shaping theory may effectively restrict the substrate bounce of CCD. Moreover, the circuit simulation proves the correctness of the theory. After the wave-shaping process to CCD driving circuits, the test results of CCD signals obviously excel those without wave-shaping. The circuit test also shows that the substrate bounce's disturbance to CCD signals is effectively restricted. The test proves the feasibility of the engineering about wave-shaping, providing a scientific theory for the focal plane high-speed driving circuit design in the future.
