基于FPGA的中频电源的任意占空比的n分频器设计

摘要

In digital logic circuit design of the intermediate frequency power supply based on FPGA,it often encounters different frequency signals and the system itself of the vibration source are often unable to meet the design requirement. This paper presents a method which can realize a kind of method of arbitrary duty ratio and arbitrary integer frequency, and taking 5000 frequency as an example, this paper introduces to use Verilog HDL hardware description language which design frequency divider of FPGA in QUARTUS Ⅱ 9.0 software. The program simulate and test through the QUARTUS Ⅱ 9.0, the experimental results meet the design requirements.%在基于FPGA的中频电源的数字逻辑电路的设计中,常会遇到不同频率的信号,而系统自身的震荡源往往不能满足设计者的要求.本文给出了一种能实现任意占空比任意整数的分频方法,并以5000分频为例,介绍了在QUARTUSⅡ9.0软件下,用Verilog HDL硬件描述语言设计FPGA的分频器.程序通过QUARTUSⅡ9.0仿真和测试,实验结果满足设计要求.
