CCD driver with tunable integration time and frequency based on FSM

VHDL has many advantages,such as simpleness,high efficiency and good stability,in achieving finite state machine(FSM).According to this,the paper presents a new approach to achieve linear CCD driver with tunable integration time and frequency.The approach is based on CPLD and FSM to achieve the key driving circuit,and it can effectively overcome the shortcomings,such as lack of flexibility,the cumbersome process and complex circuit structures in many current driving methods.The results show that the approach not only owns simple principle which is easy to achieve,but also has good flexibility and is convenient for debugging.
