WebBipolar Junction Transistor Concepts Forward Active NPN BJT Operation VC > VB > VE Fundamentals • A BJT is often considered to be a current amplifier because a small current entering the base will typically result in a large current into the collector. Or we can say that: IC = β IB, where β is a large number, typically greater than 100. WebCurrent Gains in BJT: There are two types of current gain in BJT i.e. α and β. Where. I E is the emitter current; I C is the collector current; I B is the base current; Common Base Configuration: Common Base Voltage Gain. In common base configuration, BJT is used as voltage gain amplifier, where the gain A V is the ratio of output voltage ...
WebMay 8, 2024 · As you can see in figure 4, there are three operating regions of a BJT, cutoff region, saturation region, and active region. The breakdown region is not included as it is not recommended for BJTs to operate in this region. Figure 4. BJT Operating Regions. I C vs. V CE curve for different values of I B.
