The pn junction joining the base region and the emitter region is called the base-emitter junction. The pn junction joining the base region and the collector region is called the base-collector junction. The transistor, as we have seen in the previous chapter, is a three-terminal device. Representing the basic amplifier as a two port network as in figure 9.1, there would need to be two input and two output terminals for a total of four. This means one of the transistor terminals must be common to both the input and output circuits.3. TRANSISTORS AND TRANSISTOR CIRCUITS 3.1. Double junction 3.1.1. Emitter, collector and base In its essence, a transistor consists of two diodes arranged back to back: Transistors can be either n-p-n or p-n-p.
