Pnp common base transistor
WebSimplified cross section of a planar NPN bipolar junction transistor 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. WebIn electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer . In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both ...

WebLet's see the work of the NPN and PNP transistors. The image above shows the circuit diagram of the NPN transistor. The emitter-base junction receives pre-voltage while the collection-base junction receives the inverse pre-voltage. The inverse voltage \(V_{EC}\) is higher than the front voltage \(V_{EB}\). The NPN transistor has a lot of doping. WebOne advantage over the Darlington pair is that the base turn-on voltage is only about 0.6 V, or about half of the Darlington's 1.2 V nominal turn-on voltage. ... which uses 3 NPN transistors and 1 PNP transistor, was advantageous because for decades the most common small signal transistors were germanium PNPs (silicon PNP power transistors were ...
