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.

What are the characteristics of a BJT at the cutoff and saturation regions?

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. Webelectronics). Then bipolar transistors have the ability to operate within three different regions: • 1. Active Region - the transistor operates as an amplifier and . Ic = β.Ib • • 2. Saturation -the transistor is "fully ON" operating as a switch and . Ic = I(saturation) • • 3. Cut-off -the transistor is "fullyOFF" operating as a ... black widow return to the sabbat

BJT (bipolar junction transistor) transistor as an amplifier

WebOperating Characteristics of Transistor Cut-off region- To operate the transistor in this region, both the junctions of BJT are reverse biased and the operating conditions of the transistor are as follows- input base current (IB) is equal to zero, hence the zero output collector current (IC). WebIn 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.
