Web11 jun. 2013 · A bjt is current controlled because Ie controls Ic. I have Ebers-Moll 1954 paper. They show a schematic model where Ic = alpha*Ie. They model the collector … 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-doped region, and a PNP transistor comprises two semiconductor junctions that share a thin n-doped region. N-type means doped with impurities (such as phosphorus or arsenic) that provide mobile electrons, while p-type me…
