How is common emitter configuration calculated?
The Common Emitter Amplifier Circuit A transistors current gain is given the Greek symbol of Beta, ( β ). As the emitter current for a common emitter configuration is defined as Ie = Ic + Ib, the ratio of Ic/Ie is called Alpha, given the Greek symbol of α.
What are the output characteristics of BJT?
The output characteristics of BJT can be divided into three areas – cut-off, saturation and active region. In the cut-off region both collector-base and emitter-base pn-junctions are reverse-biased – transistor is off.
What is BJT common emitter characteristics?
Saturation Region: Base-emitter junction is forward biased and Collector-base junction is forward biased. Active Region: Base-emitter is junction forward biased and Collector-base junction is reverse biased. Breakdown Region: IC and VCE exceed specifications and can cause damage to the transistor.
What are the characteristic curves of a BJT?
In the linear (or active) region the curves would ideally be horizontal straight lines, indicating that the collector behaves as a constant current source independent of the collector voltage, as illustrated in the hybrid-π model (i. C = βi. B).
What are the output characteristics of a common emitter?
For common emitter output characteristics, it curves between collector current (Ic) and collector-base voltage (Vcb) at a constant base current (Ib). You can see the output characteristics curves above.
What is base amplification factor of common emitter?
For common emitter connection, the input current is base current ( Ib ) and the output current is collector current ( Ic). Base amplification factor is generally the ratio of output current to the input current.
How is the common emitter transistor configuration applied?
In common emitter transistor configuration input is applied between base-emitter junction. the output is taken from a collector-base junction. Common emitter configuration can be applied on both types of transistor, PNP transistor, and NPN transistor.
