Design of Driver Circuit for Linear CCD Based on VHDL

Heng Dai

Abstract

CCD is widely used in non-contacted measuring as a new photoelectric device.During CCD working,the design of driver circuit is one of the key technology in its application.A realization method in design of drive program for linear CCD which uses VHDL(a kind of hardware description language) is introduced and working signal of TCD1501D is analyzed.The source code of TCD1501D′s working signal is discussed.Finally,simulated verification is made using the development software of Max+Plus Ⅱ.The simulation and the result of measurement demonstrate that this method is simple,simplified and feasible.
