新工科背景下低频晶体管放大电路实验重构

Experimental Design of Low Frequency Transistor Amplifier Circuit in the Background of New Engineering

针对传统晶体管放大电路实验过程中实践效果差、设计性弱、无法更好适应目前人才培养需求等问题,以新工科为背景、逆向思维为思维情景对实验内容重新设计。通过把非线性失真问题融入到放大电路中提升了实验难度,模块化实验内容可持续激励学生自主学习的积极性,量化考核指标则保证了对学生考核的客观性。通过近几学期的实验教学,学生反响良好,教学效果突出,激发了学生的学习积极性与创新能力,契合了新工科高素质工程人才培养要求。

There are some problems in the experiment of transistor amplifier circuit in the traditional teaching process,such as poor practical effect,weak design and poor engineering etc.which cannot better meet the demand for talent training.Taking the design of low frequency amplification circuit as an example,which is based on the background of new engineering and the thinking situation of reverse thinking.The main methods are as follows:Improve the experimental difficulty by integrating nonlinear distortion into the amplifier circuit.Through the modular experimental content,the students' initiative of autonomous learning is continuously stimulated.In order to ensure the objectivity of the assessment,the assessment indicators are quantified.We introduce the transistor amplifier circuit transforming a routine experiment into an innovative experiment,which sets a reference for the future teaching.The practice shows that the electronic circuit design enhances the teaching effect and the students' practical innovation ability and learning enthusiasm,and meets the requirements of training high-quality engineering talents in new engineering.
