The following plots are examples of the relationship between beta and collector current. The basic trend is that beta decreases at the higher end of the IC range. I’ve seen plots in which beta decreases significantly at the higher end and the lower end of the ICrange, but that appears to be less common. See more We saw in the previous article that BJT beta is both simple and complex: simple, because all you need to do to calculate collector current is … See more Before we examine the operational conditions that cause variations in beta, I want to briefly discuss this parameter in relation to … See more All of the hFE vs. ICplots have different curves for different temperatures. This tells us that beta is influenced not only by collector current but … See more You definitely can’t change the physical dimensions and doping concentrations of a purchased transistor, but you still can exert some influence over the value of the transistor’s beta, … See more 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.
