摘　　要：　通过对波形数据存储方式的改进,利用现场可编程门阵列(FPGA)设计的逻辑波形产生电路,与高压驱动电路相结合,实现了彩色等离子体显示器(PDP)所需的高压脉冲序列波形。实验结果表明,采用同步设计的电路系统减少了波形的存储容量。该电路工作稳定可靠,输出的波形光滑无毛刺,而且可以很灵活地修改逻辑波形,从而降低了PDP研发成本,缩短了研发周期。A logic waveform generation circuit based on FPGA is presented By combining this circuit with a highvoltage driving circuit,a highvoltage pulse sequence generation circuit used in colorPDP is realized Results from experiment indicate that the circuitry using synchronous structure can generate a stable and reliable driving waveform,which can be readily modified,thus reducing the volume of memory and shorten the R & D cycle
