WebThen bipolar transistors have the ability to operate within three different regions: Active Region – the transistor operates as an amplifier and Ic = β*Ib; Saturation – the transistor is “Fully-ON” operating as a switch and Ic = I(saturation) Cut-off – the transistor is “Fully-OFF” operating as a switch and Ic = 0 Webi v Characteristics - CE v CE i C v BE = v BE = v BE = v BE = Active Region Saturation Region Cuto Region As long as v CE >v CEsat, BJT is in active region. v CEsat = 0.2 V. If v CE falls below v CEsat, BJT will enter into saturation region. S. Sivasubramani EE101 - …

WebMay 27, 2014 · In Fig. shown this region exists to the right of the vertical dashed line at V CE(sat) and above the curve for I B equal to zero.The region to the left of V CE(sat) is called the saturation region. In the active region of a common emitter amplifier the collector-base junction is reverse-biased, while the base-emitter junction is forward-biased. 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.

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.
