| Abstract: | The effect of drive clock wave to transfer efficiency was analyzed based on the CCD charge transfer principle.A model of the drive clock load is builted,and analyzed the drive wave needs.Then a drive circuits was designed to prove the analysis results.Last,a image result is given by a 2 048×280 CCD worked in the rate of 300 f/s,which had fully proved the analysis and drive circuit design are right. |

| Keywords: | high frame-rate CCD vertical transfer charge transfer efficiency |
