串行A/D与FPGA在微型数据记录仪中的应用

Application of Serial A/D and FPGA in Micro-recording System

以ADS8341为例,介绍了基于FPGA使用串行输出A/D转换器实现对多通道准同步采样的方法,逻辑控制方式FPGA相比程序流程式的单片机而言,运行更为可靠,通过时序仿真和试验验证了该控制方法的正确性,系统体积小、集成度高,适用于容积小、功耗低的场合。

This paper provides the way of ANALOG-TO-DIGITAL CONVERTER that used for realizing multi-channel synchro-sampling collection based on FPGA controller.Compared to signal chip,FPGA works more stabile.By the simulation on computer and system tests,this method is verified.The small space and high integration controller is well applied in the small volume and low power system.
