The chapter delves into the characteristics of Bipolar Junction Transistors (BJTs), focusing primarily on their I-V characteristics and operational principles. It discusses the configuration of BJTs, including their junctions, typical biasing conditions, and the resulting current equations in various scenarios, such as forward and reverse bias modes. The interaction between the two junctions within a BJT is also explored, providing insights into their combined effect on transistor behavior.

What we have learnt
- BJTs consist of two p-n junctions and function through their unique characteristics and bias conditions.
- The I-V characteristic is significant for understanding the behavior of BJTs under different operating conditions.
- Current flow in BJTs is influenced by the arrangement of minority and majority carriers present in the junctions.
Key Concepts
-
Term: BJT (Bipolar Junction Transistor)
Definition: A type of transistor that uses both electron and hole charge carriers, consisting of two p-n junctions.
-
Term: IV Characteristic
Definition: The relationship between the current flowing through the BJT and the voltage across its terminals, which is crucial for understanding its operation.
-
Term: Bias Conditions
Definition: The external voltages applied to the junctions of a BJT, affecting its operating state, such as forward or reverse bias.
-
Term: Minority Carrier
Definition: Charge carriers in a semiconductor that are present in lesser concentration compared to majority carriers, playing a crucial role in current conduction.
