摘　　要：以Atmel公司的面阵CCD-TH7888A图像传感器为例,在研究了CCD结构和驱动时序图的基础上提出基于FPGA的驱动脉冲设计方法和硬件电路实现。使用VHDL语言对驱动时序发生器进行了硬件描述,并采用Quartus 5.0对设计的驱动时序发生器进行仿真。试验结果表明,涉及的驱动电路可以满足面阵CCD-TH7888A的各项驱动要求。The design and implementation of CCD image sensor digital system is introduced. Taking CCD image sensor TH7888A produced by ATMEL as an example, the FPGA-hased hardware driving design is proposed by studying the structure and driver schedule of CCD device. The hardware module and its circuit diagram of the driver are studied, the hardware description is given for the driving schedule generator by VHDL, and then the pulse signal needed by CCD is generated, the designed generator is simulated with Quartus 9.0. The experimental results show that the designed generator can meet the demand of the CCD-TH7888A.
