二、晶体管调谐放大器的设计由于晶体管有内部反馈,因此在作为调谐放大器运用时就会引起电路的自激振荡、谐振曲线的畸变以及输入、输出回路调谐时的相互影响.所以设计晶体管调谐放大器时首先就要设法克服这种内部反馈的影响.通常有两种方法.一种是所谓单向化(中和)的方法,就是在外电路中加一反馈电路来抵偿晶体管内部的反馈效应,使得总的电路成为单向化.这种电设计
Second, the transistor tuning amplifier design Since the transistor has internal feedback, so when used as a tuned amplifier circuit will cause self-oscillation, the resonance curve distortion and input and output circuit tuning when the interaction. So the design of transistor tuning amplifier First, we must try to overcome the impact of this internal feedback. There are usually two ways. One is the so-called unidirectional (and) method is to add a feedback circuit in the external circuit to compensate for the feedback effect within the transistor, so that the total The circuit becomes unidirectional. This electrical design
