WebFigure 5 shows an actual BJT operating in the active region and the small signal equivalent model. Do not confuse this with a MOSFET in saturation, which behaves similarly to the BJT in the active region. Figure 5: Active Region, B-E Diode is Forward Biased and B-C Diode is Reverse Biased (iii) Cuto Region WebThe saturation region does include the scenario when CB is forward biased but I don't think this is particularly helpful - the saturation region (or close to it) must still encompass normal transistor amplification and, as far as I know, this cannot happen when collector and base are forward biased. how many 3 go into 30

WebJan 24, 2024 · This mode of operation is the active or linear region of operation in the BJT transistor characteristic curve. By increasing the V CE beyond 0.7v, the collector current remains constant for a given value of base current I B. Increasing the V CE can cause a very slight increase in I C because of the widening of the base-collector depletion region.
