BJTtransistoria
BJTtransistoria refers to bipolar junction transistors, fundamental semiconductor devices used for amplification and switching. A BJT consists of three layers of semiconductor material, forming two PN junctions. These layers are typically made of silicon and are doped with impurities to create either P-type (excess holes) or N-type (excess electrons) material. The three terminals of a BJT are the emitter, base, and collector.
There are two main types of BJTs: NPN and PNP. In an NPN transistor, the emitter and
The base region is intentionally made very thin and lightly doped. A small current flowing into or
