1、 多用函数信号发生器的设计 2012 年 5 月 多用函数信号发生器的设计 The Design of Multi-functionsignal Generator I 摘 要 函数信号发生器是指能自动产生方波、正弦波、三角波等电压波形的 仪器, 它在实验及科学研究中得到了广泛应用。本课题的任务是设计一个 函数信号发生器，使其能自动产生方波、三角波以及正弦波。本论文主要 针对函数信号发生器进行论述，它基本可分为四部分：第一部分主要是对 设计中应用到的一些模电数电方面的知识如电压比较器积分器，差分放大 器等进行简单介绍;第二部分的主要内容是提出了以下两种设计方案:第 一种方案是基于单片集成芯片M

2、AX038函数信号发生器的设计,第二种方案 是基于晶体管、运放 IC 等函数信号发生器的设计,并且对这两种方案的优 点和缺点进行分析比较,最后确定采用第二种方案来完成函数信号发生器 的设计。第三部分就具体介绍了我的设计方案基于晶体管、运放 IC 等 函数信号发生器的设计,它是本文的核心,该部分讲述了性能指标、原理框 图、以及如何通过参数计算来确定设计电路等几个方面的内容;文章第四 部分就主要介绍了调试安装的方法,并对设计中出现的故障进行了简要分 析。 关键字：函数信号发生器 差分放大器 积分器 II Abstract The function signal generating device

3、is refers can automatically have voltage waveform the and so on the square-wave, sine wave, triangle wave instrument, it obtained the widespread application in the experiment and the scientific research. This topic duty designs a function signal generating device, enables its automatically to have t

4、he square-wave, the triangle wave as well as the sine wave. The present paper mainly aims at the function signal generating device to carry on the elaboration, it is basic may divide into four parts, the first part mainly is to some mold electricity number electricity aspects knowledge like voltage

5、comparators which designs applies, the integrator, the differential amplifier and so on carries on the simple introduction; The second part of main content was proposed following two kind of design proposal: The first kind of plan is based on the monolithic integrated chip MAX038 function signal gen

6、erating device design, the second kind of plan is based on the transistor, transports puts function signal generating device the and so on the IC design, and carries on the analysis comparison to these two kind of plans merit and the shortcoming, finally determined uses the second kind of plan to complete the function signal generating device the design. The third part specifically introduced my design proposal - based on the transistor, transports puts function signal generating device the
