WebDec 26, 2015 · gbarry. 8,435 21 31. In saturation region (where Vce<0.2V) the "beta" is much lower than in the active region (where Vce>0.2V); this makes Ic much smaller for a fixed base current in the saturation region. When one saturates transistor by achieving Vbe>=700mV, from now on the transistor will have a low beta since it is now in … WebThere are different types of transistor amplifiers operated by using an AC signal input. This is interchanged between the positive value and negative value, hence this is the one way of presenting the common emitter amplifier circuit to function between two peak values.

Many technical references will tell you that bipolar junction transistors (BJTs) are current-controlled devices: collector current is controlled by base current. This concept is reinforced by the notion of “beta” (β), the ratio between collector current and base current: β = I C I B β = I C I B. dyche studio
