Design and realization of the time sequence driving circuit for a kind of linear CCD based on CPLD and VHDL

CCD is a new semiconductor photoelectric device widely used in some fields. The design of the time sequence driving circuit of CCD is a crucial problem of its application. VHDL and CPLD are used together to complete the design of the time sequence driving circuit of CCD. Some of the codes with VHDL are given. Timing simulation of circuit running on MAX+plus Ⅱ is presented. Some problems of VHDL design are analyzed and studied.
