基于Multisim的西勒振荡器设计与仿真

针对解决西勒振荡器传统讲授理论性较强,缺乏直观性,教学效果不理想的目的,采用了引入电路仿真软件Multisim进行设计、分析的方法 ,通过电路频率特性、反馈特性、负载特性、频率稳定度试验仿真,得出振荡频率为404.978 k Hz、峰峰值为8.00 V的西勒振荡器电路设计满足要求,仿真结果与理论分析基本一致。虚拟软件与传统讲授结合,加深了学生对高频电子线路理解和记忆,提高了学习效率。

Design and simulation of Seiler oscillator based on Multisim

The traditional teaching of Seiler oscillator, which is too theoretical and for lack of practice, results in the inefficiency in teaching. The introduction of Multisim, the circuit simulation software, can realize the design and the analysis process, be means of simulating the circuit frequency response, feedback, load characteristic and frequency stability,which arrives at the conclusion that the Seiler oscillator circuit with the frequency of 404.978 kilohertz, peak-to-peak value of 8.00 volt can meet the requirements, and the simulation results are consistent with the theoretical analysis. Virtual software combined with traditional teaching can help to deepen the students understanding of high frequency electronic circuit, and improve their learning efficiency.
