摘要
以典型的线阵CCD图像传感器件TCDl32D为例,设计和开发了一种线阵CCD驱动电路。电路主要采用了复杂可编程逻辑器件(CPLD),充分发挥其"可编程"的技术特性,为用户提供了丰富的接口信号。介绍了该驱动电路的主要特性、工作原理和驱动时序的设计思想,阐述了逻辑设计原理,给出了CPLD实现电路和时序仿真图形.验证了CPLD技术的可行性。实验结果表明:在该驱动时序作用下,驱动电路可以完全正常工作。
With the example of TCD132D,a new linear CCD driver is designed to meet the measurement requirements in engineering fields.This driver is developed on the basis of CPLD,and rich interface signals are provided for users with the help of the programmable technology of CPLD.Its key features,principle and design ideas of the timing sequence are presented in detail.The login design principle,the realizing circuit of CPLD and its waveform of time order simulation were given in details.It is proved by experiments that the whole measurement system can work well and its precision meets requirements when this driver is integrated into another measurement circuit.
