晶体管多级放大电路教学初探

资 源 简 介

晶体管多级放大电路是“模拟电子技术”课程当中三种组态基本放大电路的综合应用,其放大增益与信号源和负载的特性及各级输入输出电阻有着密切联系,这部分内容实用、重要、综合性较强。我们针对上述问题在教学中采用问题式教学法并配以Muhisim仿真,将问题贯穿教学始终,突破传统教学方法,有利于将抽象的问题形象化,提高学生学习兴趣。

Multi-stage amplifier circuit is integrated application of three basic configuration amplifiers, and its gain is closely linked to the characteristics of the signal source , the load , and the input and output resistance of various circuit. This section is useful, compresive and important. Question teaching method with Multisim simulation is used in teaching process in which traditonal teaching methods are brokenthrong. It will make abstract problem visu- alized and improve the interest of students.
