基于Pspice单调谐放大器的分析与设计

An Analysis and Design of Resonant Amplifier Based on Pspice Simulation

在进行谐振放大器的质量指示分析和电路设计参数的选择的教学过程中,学生普遍反映较难,为了激发学生的学习兴趣和提高教学质量,在教学中引入了Pspice仿真软件。一方面对单调谐放大器的增益、通频带、选择性以及相互关系进行了仿真分析;另一方面给出放大器的设计指标,采用参数扫描与Optimezer Parameters优化模块相结合的方式,对电路进行了优化设计,设计结果表明在误差范围内完全满足指标要求,这为以后的理论教学和实验教学提供了一种新的方法和途径。

It is difficult for students to understand the quality indicating analysis of the resonant amplifier and to choose the parameter of the circuit layout. During the teaching process, emulation software is applied in it to ignite the enthusiasm for study and to improve the teaching quality. On one hand, an emulation analysis is conducted for the gain, band-pass and selectivity of the resonant amplifier, and their relationship. On the other hand, index of the design for the amplifier is displayed and the optimization for the circuit is designed by the combination of scan of the parameter and the optimizer parameters. The result shows that the design, in the range of errors, accords with the requirement. This art of teaching provides a new approach for the theoretical teaching and experiments.
