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 […]
