Study Notes
Bipolar Junction Transistors (BJT) Chapter Outline
- Chapter 4 covers the structure and connections of Bipolar Junction Transistors (BJT)
- The BJT is constructed with three doped semiconductor regions: emitter, base, and collector
- Two types of BJTs are shown: npn with two n regions separated by a p region, and pnp with two p regions separated by an n region
- The term "bipolar" refers to the use of both holes and electrons as current carriers in the BJT structure
- The transistor has three sections of doped semiconductors: emitter, base, and collector
- The section on one side is the emitter
- The BJT operates as an amplifier
- The common base, common emitter, and common collector connections are discussed
- The BJT is constructed with three doped semiconductor regions separated by two pn junctions
- The BJT structure is shown in the epitaxial planar structure in Figure 4.1
- The BJT connections and construction are essential for understanding its functionality
- The chapter includes practical exercises and summaries for better understanding of the BJT structure and connections
