Multisim10在单管共射放大电路中的应用

摘要

利用Multisim 10仿真软件对单管共射放大电路进行了计算机辅助教学.采用直流工作点分析了电路静态工作点的设置.利用温度扫描和参数扫描分析了温度对静态工作点以及电路参数对输出波形的影响.对电压增益、输入电阻和输出电阻的仿真测试结果和理论计算基本响合.研究表明,利用Multisim 10强大的分析功能对电于电路进行计算机仿真,可以提高教学质量和教学效果.%Mulisim 10 simulation software was used for computer aided teaching. The quiescent operating point was set by using DC operating point. The influence of temperature on quiescent operating point and circuit parameter on output voltage waveform were analyzed by using temperature scanning and parameter scanning. The simulation test of voltage gain, input resistance and output resistance coincide with theoretical calculation loasically. The results show that using the powerful analysis capability of Multisim 10 , the computer simulation of electronic circuits can enhance the teaching quality and teaching effect.
