WebAug 16, 2024 · In the active region of a bipolar junction transistor, the transistor works as an amplifier. Saturated Region of a Bipolar Junction Transistor In the saturated region the Bipolar Junction Transistor passes a saturated current after reaching a maximal value of threshold voltage. WebTo analyze BJT circuit with D.C. sources, we mustfollow these five steps: 1. ASSUME an operating mode 2. ENFORCE the equality conditions of that mode. 3. ANALYZE the circuit with the enforced conditions. 4. CHECK the inequality conditions of the mode for consistency with original assumption.

WebThe ﬁnal region of operation of the BJT is the “forward active” region. It is in this region that the transistor can act as a fairly linear ampliﬁer. In this region, we see that: * 0.2 < Vce < Vcc ; where Vcc is the supply voltage * Ib > 0 and Ic > 0 * Vbe >= 0.7V WebActive region This is the region in which transistors have many applications. This is also called as linear region. A transistor while in this region, acts better as an Amplifier.
