Explain the construction and working of bipolar junction transistor (BJT). [5]
A Bipolar Junction Transistor (BJT) is a three-terminal device formed by combining two PN junctions in a specific manner. It is called "bipolar" because both holes and electrons participate in conduction. A BJT consists of three doped semiconductor regions sandwiched together, forming either: - N...
