Driving Circuit Design of Line Array CCD Based on the CPLD Technology

针对以往设计的电荷耦合器件(CCD)驱动电路存在着体积大、易受干扰和工作频率低的缺点,设计出一种基于复杂可编程逻辑器件(CPLD)技术的CCD驱动电路,可用于不同型号的CCD,同时提高了整个系统的稳定性和工作的效率.仿真结果表明,该电路具有一定的实用价值.

Aimed at the shortcomings that the driving circuit of linear CCD has large size and liable to be inter-fered, a CCD driving circuit based on CPLD is designed in this paper, which can be applied to CCD components of various models. In this way, the circuit is simplified and the stability of system, as well as the operating efficiency, can also be uplifted. It shows that the circuit is of applicable value.
