WebBipolar junction transistors are called bipolar because they use both electrons and holes to conduct. As current passes through the transistor, both n-type and p-type materials contribute to electric current. This is in contrast with unipolar devices like field effect transistors (FETs), which use only one type of charge carrier (either ... WebAnswer (1 of 2): Alright let me just give a brief introduction to bipolar transistors since this topic can easily cover a thorough undergraduate ECE course. Bipolar transistors are essentially two np diodes connected by a base. Most commonly, you’ll see them as npn transistors, but it’s not unhe...

WebSimilarly, the pnp transistor consists of an n-type region located between two p-type regions. Thus, the BJT transistor consists of two pn junctions, connected back-to-back. These are called the emitter-base junction (EBJ) and the collector-base junction (CBJ). The circuit symbols for both kinds of BITs are shown in Figure 1. WebThe BJT is a three terminal device and it comes in two different types. The npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1. The BJT is fabricated with three separately doped regions. The npn device has one p region between two n regions and the pnp device has one n region between two p regions.
