基于运放的电子电路综合实验项目设计

Design of Electric Circuit Comprehensive Experiment Project Based on Operational Amplifier

电子电路综合实验对提高学生的电子系统设计和实践能力起着重要作用。该文提出了一个运算放大器综合运用的案例,基本囊括运算放大器的典型电路,根据案例指标要求,通过理论分析和计算,设计电路参数,并利用EDA软件Multisim仿真验证;然后进行了实际测试,分析了问题产生的原因及解决办法。从案例的提出到理论设计、实际调试,全面展示了实验项目研究的方法,可为其他高校开设电子电路综合实验提供一定的借鉴。

Electric Circuit Comprehensive Experiment plays an important role on improving the electronic system design and practical ability of students,the quality of the experiment and the experimental effect are closely related.Firstly,we designed a project on integrated application of operational amplifier case which includes the typical circuits of operational amplifier skillfully.Secondly,according to the requirement of project,designed circuit parameters through theoretical analysis and calculation,then used Multisim of EDA softw-are to simulate.Finally,the problems encountered during the experiment were analyzed.It comprehensively introduced the experimental research methods from project selection to theoretical design and practical adjustment.Then the actual test was conducted to analyze the causes and solutions of the problems.From the proposal of the case to the theoretical design and practical commissioning,the method of experimental project research is fully demonstrated,which can provide reference for other universities to set up the comprehensive experiment of electronic circuits.
