WebOct 8, 2015 · Now your assumption about the emitter being connected to a P region, the base to a N region and the collector to a P region is correct. And keep in mind that a Si atom has 4 valence electrons and that hole concentration will be in the order: emitter > collector > base and reverse for electron concentration.The calculations are quite easy to do. BJTs consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These regions are, respectively, p type, n type and p type in a PNP transistor, and n type, p type and n type in an NPN transistor. Each semiconductor region is connected to a terminal, appropriately labeled: emitter (E), base (B) and collector (C). The base is physically located between the emitter and the collector and is made from lightly do… small caterpillars in my house

WebApr 8, 2024 · A transistor is a semiconductor device, which is formed by fusing two junction diodes. When the anodes of the two diodes are fused, the transistor is called an n-p-n transistor. When the cathodes of the two diodes are fused, the transistor is called a p-n-p transistor. A transistor consists of three parts – a collector, an emitter and a base. WebA BJT is made of a heavily doped emitter(see Fig. 8–1a), a P-type base, and an N-type collector. This device is an NPNBJT. (A PNPBJT would have a P+emitter, N-type base, and P-type collector.)
