如何利用新兴起的FPGA芯片设计出生产生活中常用的仪器是电路设计中的重点和难点。提出了一种新的实验思路,基于FPGA开发平台设计了一款数字示波器。对VGA控制原理和电路设计、A/D控制电路设计、D/A控制电路设计三个模块进行了详细分析,其中A/D控制电路主要用TI公司生产的TLC549芯片实现,D/A控制电路通过一个串并联电阻网络来模拟实现。整个设计操作简单,易于调节,显示直观。通过实验测量和对比,具有良好的精度和采样率,符合对数字示波器的简易要求,具有一定的应用前景。

How to make use of emerging FPGA chips to design the frequently-used instruments are the circuit design of the key and difficult point.This paper presents a new experimental ideas,a digital oscilloscope is designed based on the FPGA development platform.The VGA control principle and circuit design,A/D control circuit design and D/A control circuit design are analyzed in detail.The A/D control circuit is mainly realized by the TLC549 chip produced by TI Company,and the D/A control circuit is achieved by a series-parallel resistance network.The entire design is simple,easy to adjust,display intuitive.Through experimental measurement and comparison,with good accuracy and sampling ratio,in line with the simple requirements of digital oscilloscope,has a certain application prospect.
