集成运算放大器的教学仿真实践与应用研究

Research on teaching simulation practice and application of integrated operational amplifier

集成运放在电子技术课程教学中是一个重要内容,在电路设计中应用广泛。集成运放工作在线性区可以实现信号放大、信号运算、滤波等;而工作在非线性区时具有电压检测、电压比较器等功能。文中利用集成运放实现两个信号的求差运算、信号变换,通过Multisim电路仿真验证让学生对实际结果有直观认识,对集成运放的应用有更深入的掌握。

Integrated operational amplifier is a very important content in electronic technology teaching and it is widely used in circuit design. When working in the linear region, the integrated operational amplifier can work to realize signal amplification, signal operation, filtering and so on. And when working in a non-linear region, voltage detection, voltage comparator, and other functions can be realized. In this paper, we use the integrated operational amplifier to achieve the difference operation of the two signals, as well as the signal transformation. Through Multisim circuit simulation, the students havea very intuitive understanding of the actual results, and havinga deeper understanding of the application of integrated operational amplifier.
