| 摘 要： | 负电阻不是实际存在的电路器件,但它可以通过其它的电路元件来实现。通过给出负电阻的实现方法,给出了运算放大器工作于线性区的条件。讨论了用Multisim实现负电阻的仿真和分析的方法,得出负电阻和负电阻的串并联连接以及负电阻和正电阻的串并联连接电路中,负电阻的处理方法与正电阻一致的结论。用Multisim实现负电阻的仿真和分析,作为一个电路的虚拟或仿真实验,可以为电路实验教学提供帮助。

| Abstract: | A negative resistance is not a component of the real circuit,but it can be realized by using other circuit components.In this paper,the realization of negative resistance was discussed and Multisim software was used to simulate and analyze the circuits with negative resistance.In the equivalent transformation of the circuit,it can just treat the negative resistance as the positive resistance and use the Ohm theory.The result of this analysis can be the reference for teaching the circuit course.It is helpful to design virtual experiment of negative resistance. |
