一种小信号音频功率放大器电路参数的设计

The Design of A Kind of Small Signal Voice-Power Amplefier Circuit Parameter

功率放大器在大信号状态下工作,输出信号易于产生非线性失真,输出功率越大,失真越严重。本文通过一个小信号功放的电路设计,提出一种在非线性失真允许的范围内获得最大输出功率的方法。模拟仿真与实际应用都证明这种分析方法的有效性,为实际电路设计与分析提供了一种参考。

When power arnplefier works at a big signal, the output signal will easily lead to be nonlinear distortion, and the bigger the power is, the more serious the distortion will be. Through a circuit design on a small signal power amplefier, this paper gives out a way about bow to obtain the biggest power within a distortion limit. Mutation and real-time application all prove the effect of this analysis way, so it can provide a fundamental reference for real-time circuit analysis and design.
