These electrons will attempt to recombine with the majority base holes, however, because the base is physically thin and lightly doped, only a small percentage of the injected electrons will recombine with base holes and exit the base terminal back to ground. Transistors Bipolar Junction Transistors (BJT) Transistor Basics A Bipolar Junction Transistor is a three layer (npn or pnp) semiconductor device. As long as there is sufficient potential from the emitter supply, the electrons will be pushed into the base.

The base-emitter depletion creates an energy hill just as it did with a single PN junction. Bipolar junction transistor (BJT) is the type of transistor and three-terminal semiconductor device, which has two p-n junctions. Semiconductors Bipolar Junction Transistors Introduction to Bipolar Junction Transistors (BJT) Vol. From the left side of the diagram, electrons exit the emitter supply and enter the N emitter. Download PDF LAB 2: BIPOLAR JUNCTION TRANSISTOR Main objective: Construct a common emitter amplifier using bipolar junction transistor Introduction Bipolar Junction Transistor (BJT) A bipolar junction transistor also known as BJT is a type of transistor that is made of two type of semiconductor in contact. \): Forward-reverse bias, electron flow.Įlectron flow will facilitate this explanation so we'll draw the current directions using dashed lines.
