二、半导体三极管低频小信号网络特性半导体三极管在电路中使用时可以有三种不同的联接方式即:共基极、共发射极及共收集极.见图14.无论那种电路联接,在正常工作时都必须使发射结处于正向偏压,收集结处于反向偏压.由于电路的联接形式不同,它们的静态特性也略有不同,见图15.从三种联接形式的电路工作情况,不难了解它们的特性.
Second, the semiconductor transistor low-frequency small signal network characteristics Semiconductor transistors can be used in the circuit when there are three different ways to connect that: a total of base, a total of emitter and a total of collector shown in Figure 14. No matter the kind of circuit connection, in normal work The emitter junction must be forward-biased and the collector junction is reverse-biased. The static characteristics of the circuit are slightly different due to the different types of connections of the circuits, as shown in Figure 15. From the circuit behavior of the three types of connections, It is not hard to understand their characteristics.
