WebThink of the collector emitter junction of the transistor as being like a variable resistor, the thing that controls it is the base current. When a transistor is conducting as much as the collector load will allow it is said to be saturated (or the pot turned down to zero), more base current won't give you any more collector current.

WebBecause base–emitter voltage varies as the logarithm of the base–emitter and collector–emitter currents, a BJT can also be used to compute logarithms and anti-logarithms. A diode can also perform these nonlinear functions but the transistor provides more circuit flexibility. Avalanche pulse generators WebMay 22, 2024 · The base-collector junction is reverse-biased, therefore \(V_{CB}\) is large. Conventional current flows into the collector and base, and out of the emitter. We can also define a couple of transistor performance parameters. The ratio of collector current to emitter current is called \(\alpha \) (alpha). \(\alpha \) typically is greater than 0.95.

WebMay 22, 2024 · For an NPN transistor that means that the collector must be at the highest potential, the base somewhat lower and the emitter at the lowest potential of the three. One way of doing this is to apply the usual positive supply to the collector, but instead of using a second potential at the base, the base is tied to ground through a resistor.
