In the circuit of Fig. P2.24 let RB 5 RC 5 RE 5 10 kV, and let the BJT have F 5 100 and R 5 5. Moreover, to simplify calculations somewhat, assume that when either junction is fully forward biased, it drops 0.7 V regardless of the BJT’s operating mode. Identify the BJT’s operating region, and estimate its terminal voltages and currents (magnitudes and directions!) if: (a) VCC 5 10 V, VBB 5 5 V, and VEE 5 0 (ground). (b) VBB 5 VCC 5 5 V, and VEE 5 0. (c) VEE 5 10 V, VBB 5 5 V, and VCC 5 0. (d) VBB 5 VEE 5 5 V, and VCC 5 0. (e) VBB 5 0 V, VCC 5 10 V, and VEE 5 5 V. Hint: for each individual case, you may wish to reorient the circuit so that positive voltages appear at the top of the fi gure, and ground at the bottom.
