摘要
针对传统西勒振荡器实验缺乏设计性、教学模式陈旧、教学效果不理想的情况,提出通过Multisim10对西勒振荡器参数进行设计。仿真后观察起振过程和实验的方法,分析晶体管静态工作点,反馈系数、负载变化对电路起振,振荡幅度的影响,仿真结果与硬件实验结果一致。实践证明:引入软件仿真使学生从实践中进行了探索式的学习,增强了学生解决实际问题的能力和设计电路的能力。
The traditional Sillery oscillator experiment is lack of designability. The teaching mode is old,and the teaching effect is not ideal. So the Multisim10 for the design of sillery oscillator parameters is proposed. The students observe the start-up procedure after the simulation and analyze the impact of start-up and the oscillation amplitude by the static working point, coefficient of feedback and load fluctuation. The simulation results are consistent with the hardware experimental results. The experiment has proved that： introducing the software simulation enables the students to explore the type of learning from practice, and enhances the students’ ability to solve practical problems and the design circuits.
