摘　　要：介绍了行间转移面阵CCD芯片KAI-1010M的内部结构和驱动时序,采用新方法和低成本器件设计了该CCD芯片的驱动电路,把电源和电机控制的脉冲宽度调制技术引入CCD驱动电路,采用超高速运放驱动高速负压信号以减小其上升沿和下降沿时间,达到高速低成本驱动要求,解决了驱动设计中的技术难点。实验结果表明,此CCD驱动系统采用低成本的器件,性能好、成本低、能够同时输出两路CCD电压信号,数据输出速率达15 frame/s,满足空间测绘相机的系统设计要求。若进一步改进电路,数据输出速率可达27 frame/s。After introducing to the inner structure and the driver timing of a interline area-CCD KAI- 1010M briefly, a high speed and low cost CCD driver circuit used in digital space survey camera was designed in a new way. In order to resolve the technical difficulties, the pulse width modulation tech- nology usually used in power supply and motor control was introduced into the CCD driver circuit and a ultra-high speed operational amplifier was adopted to reduce the rise time and fall time of high speed negative signal. Experimental results show that the CCD driver system can output two groups of CCD signals simultaneously at data output speed of 15 frame/s, which can meet the requirements of the camera system because of its good function and low cost. If the circuit is improved further, the CCD driver system can output two groups of CCD signals at data output speed of 27 frame/s.
