QUESTION 3 (a) In a Bipolar Junction Transistor (BJT), there are 3 possible modes of operation which are active, saturation and cut-off region. Complete Table Q3(a) whether the Base- Collector (B-C) and Base-Emitter (B-E) junctions are in forward-biased or reverse biased for each mode. Assume the BJT is the NPN type. (b) Mode Forward-active Saturation Cut-off Junction (i) For the Bipolar Junction Transistor (BJT) amplifier circuit in Figure Q3(b). Determine the DC values of IBQ, Ico, VCEQ, Vc and VE 0.6 ΚΩ Table Q3(a) Base-Collector (B-C) V₁o M (C3, SP3) [8 marks] The addition of the emitter resistor to the DC bias of the BJT provide improved stability. Explain that
