集成运算放大器输出电压求解方法的教学探究

Teaching exploration of the output voltage solving solution of integrated operational amplifier

集成运算放大器是模拟电子技术课程中重要的器件,已知输入电压和电路各元器件的值求解输出电压是集成运算电路的一个重要知识点,分别用虚短和虚断结合法、理论推导法求解集成运算放大器的输出电压,并对这两种方法进行了总结,以帮助学生更好地掌握该知识点.

Integrated operational amplifier is an important device in the analog electronic technology course. Solving the output voltage of integrated operational amplifiers when the input voltage and values of devices are known is a key knowledge point. The output voltages of integrated operational amplifiers are solved using the combination of virtual short circuit and virtual open circuit, and theoretical derivation method. The summery of the two methods are given to help students master them well.
