Let’s explore the biasing and operation of NPN and PNP transistors to understand how proper transistor biasing controls current flow, establishes the operating point (Q-point), and enables a bipolar junction transistor (BJT) to function as an amplifier or an electronic switch. The operation of a transistor depends on the biasing of its two PN junctions […]

Structure of NPN and PNP Bipolar Junction Transistors
The Bipolar Junction Transistor (BJT) is one of the most important semiconductor devices used in modern electronic circuits. It consists of three semiconductor regions known as the emitter, base, and collector, which are formed by joining either two n-type regions with one p-type region or two p-type regions with one n-type region. Depending on this […]
