WebMay 22, 2024 · Effectively, when a BJT saturates, \(\beta\) is forced to drop to whatever value is needed to produce \(I_{C(sat)}\). We just need to make sure that even the smallest \(\beta\) is large enough to cause saturation. 4.7.1: The Saturating Switch. A good example of this is the saturating LED driver circuit shown in Figure \(\PageIndex{1}\). To ...
