【Abstract】 In order to obtain multifold frequency driving of linear CCD on single circuit,the structure theory and driving pulses of μPD3575D linear CCD are analyzed.The driving circuit of μPD3575D linear CCD is designed based on selected switch which controls driving frequency of μPD3575D and complex programmable logic device(CPLD)whose inner logic circuit is given.Results of simulation and experiment indicate that multifold driving pulses can be obtained in the driving circuit,and construction of the circuit is simple whose practicability is wide,which offers theoretical basis of realizing the driving integration circuit of multi-type linear CCD.更多还原
