四、对输出级失真的分析在晶体管音频功放系列谈(四)中,曾经指出,通过巧妙地运用较为常规的电路,能够把小信号级的失真保持在很低的水平上,并能达到与闭环输出级失真可以忽略不计的程度。在下次系列谈(六)所讨论的内容中,也将说明通过采取一些比较不为人知但却是直接了当的方法,还能有效地消除 VAS 的负载失真、电源干线退耦失真、感应失真、负反馈起始失真及电容器失真。这样,作 Fourth, the output-level distortion analysis In the audio amplifier series (4) of the transistor, it has been pointed out that by clever use of the more conventional circuits, small signal-level distortion can be maintained at a very low level and can reach Closed loop output stage distortion is negligible. In the next series (6) of the discussion, will also show that by taking some relatively unknown but yet direct method, but also can effectively eliminate the VAS load distortion, the power supply line decoupling distortion, induced distortion , Negative feedback starting distortion and capacitor distortion. In this way, make
