WebTo simplify matters, we frequently assume a constant value (how much) for the forward biased base-emitter voltage of a BJT. Is this good engineering practice? Provide at least one pro and one con argument. Question: To simplify matters, we frequently assume a constant value (how much) for the forward biased base-emitter voltage of a BJT. Is ... 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.

WebAug 1, 2024 · Then for the AND gate the top switch must give a follower voltage with the B-E diode drop ~ 600 mV drop and this only reduces the Voh or V output-high by that much. But still a logic “1” when high. So the output will drop 2 diode drops from V2 when both NPN’s inputs are high at 6V. E.g. if V2=5V Voh=5-1.2= 3.8V.
