资料介绍

在此运用LabVIEW软件仿真了模拟电路中的典型阻容耦合共发射极放大电路,此电路有放大状态、饱和失真状态和截止失真状态。针对放大状态给出了它的静态工作点和正常的放大输出波形;针对饱和失真状态和截止失真状态给出了相应的失真波形。在典型阻容耦合共发射极电路基础上,设计了电压串联负反馈电路,验证了负反馈对整个电路输入/输出电阻及放大倍数的影响。

In this paper, a typical resistance and capacitance coupling common emitter amplifier in the analog circuit is simulated with LabVIEW software. The circuit has amplification state, saturated distortion state and cut-off distortion state. The quiescent operating point and normal amplification output waveform of the amplification state are given in this paper. The corre- sponding distortion waveform of the saturation distortion state and cut-off distortion state is also offered. The voltage series nega- tive feedback circuit is designed in this paper based on resistance and capacitance coupling common emitter circuit. The inf- luence of the negative feedback on input/output resistance and the amplification factor of the whole circuit was verified.
