Let the BJT of have F 5 150 and R 5 4. Moreover, assume that either junction drops 0.7 V when fully forward biased, regardless of the BJT’s operating mode, and that its forward current is still zero for a forward bias of 0.65 V or less. Also, read the hint of Problem 2.24. (a) If RC 5 RE 5 10 kV, RB 5 100 kV, VEE 5 5 V, and VCC 5 25 V, fi nd VBB so that VEC 5 1.0 V. (b) Reconsider the circuit of part (a), but with VEE 5 25 V and VCC 5 5 V, and fi nd VBB so that VCE 5 1.0 V. (c) If RB 5 RC 5 RE 5 10 kV, VEE 5 9 V, and VBB 5 0 V, estimate VCC so that IC > 0. (d) If RB 5 RC 5 RE 5 10 kV, VEE 5 6 V and VCC 5 0 V, fi nd VBB so that IB 5 0.75IE. What is the value of beta in this case? (e) Repeat part (d), but for IB 5 1.25IE.
