WebJan 2, 2024 · In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN (Negative-Positive-Negative) configuration and a PNP (Positive-Negative-Positive) configuration.That is: an NPN transistor and a PNP transistor types. The most commonly used transistor configuration is the NPN Transistor.We also … A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much … See more By convention, the direction of current on diagrams is shown as the direction that a positive charge would move. This is called conventional current. However, current in metal conductors is generally due to the flow of electrons. … See more Bipolar transistors have four distinct regions of operation, defined by BJT junction biases. Forward-active (or simply active) The base–emitter junction is forward biased and the base–collector junction is reverse biased. Most … See more BJTs can be thought of as two diodes (P–N junctions) sharing a common region that minority carriers can move through. A PNP BJT will function like two diodes that share an N-type cathode region, and the NPN like two diodes sharing a P-type anode region. … See more BJTs exist as PNP and NPN types, based on the doping types of the three main terminal regions. An NPN transistor comprises two semiconductor junctions that share a thin p … See more BJTs consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region.
