Web• In order to prevent the BJT from entering very deeply into saturation, the collector voltage must not fall below the base voltage by more than 400 mV. V CC I C R C (V BE 400mV) A linear relationship can be derived for VCC and RC and an acceptable region can be chosen. Deep Saturation Webmore. We have studied in the previous video that increasing the external voltage across the PN junction will not increase the current across it, it will only only produce the same number of charge carrier but number of charge carrier produced remain same. We know current is number of charges per unit time. Thus number of electrons diffusing ...

WebThe transistor can be used as a switch if biased in the saturation and cut-off regions. This allows current to flow (or not) in other parts of a circuit. Because a transistor ’s collector current is proportionally limited by its … WebThe region to the left of the knee is the saturation region. For switching applications, the BJT is most like a closed switch when it is in the saturation region, where VCE is small. It is most like an open switch when it is in cutoff, with iC = 0. A BJT is often used as a current-controlled switch, as illustrated in figure 3. high mountain forestry and equipment montanaWebIn cutoff mode, the brake is engaged (zero base current), preventing motion (collector current). Active mode - is the automobile cruising at a constant, controlled speed (constant, controlled collector current) as dictated by the driver. Saturation - the automobile driving up a steep hill that prevents it from going as fast as the driver wishes. how many 3 go into 27

"WebAnswer: When a BJT is in “cutoff”, no collector current is flowing and the “Beta” (available current gain, base to collector) is zero. When a BJT is in “Saturation” there is only a minimal collector to emitter voltage and the collector current is at it’s maximum limit. Again the “Beta” is zero. ...
