基于Multisim 13.0调谐放大器静态工作点研究.

The analysis for tuned amplifier has been carried out through Multisim 13. 0 software. The suitable components which influence quiescent point were selected by sensitivity analysis, it is a quantitative analysis. The suitablecomponents of the biasing circuit were selected by parametric scanning analysis, and the importance of setting suitable quiescent point was proved. The suitable emitter resistances were selected by parametric scanning analysis and temperature scanning analysis. Al approved the stability of amplifier. The result were visual and precise, and could prove the theory very well. It was verified that the software has powerful simulation and analysis function. With the help of the software, we can convert the traditional qualitative analysis to quantitative analysis. The analysis and design of high frequency circuit are not only more precise and credible, but also more closed to the real circuit running status. [ABSTRACT FROM AUTHOR]
