单管放大器电路解析及探讨

Analysis and Discussion of Single Transistor Amplifier Circuit

详细论述了单管放大器电路各部分元件的性能及作用,在研究静态电路时,提出了一种排除判别法来确定晶体管的正常工作状态,并设置了合适的静态工作点;在研究动态电路时,分别在空载和接入负载的情况下,解析得出合适的静态工作点能够对输出电压进行线性放大和等倍数的线性放大。

In this article,the performance and function of each part of the single transistor amplifier circuit are discussed in detail.In the study of static circuit,a method of exclusion and discrimination is proposed to determine the normal operation of transistor,and the appropriate quiescent point is set.In the study of dynamic circuit,the suitable quiescent point can be used for linear amplification of output voltage and linear amplification of equal multiple by the case of no load and large access load.
