In the pnp inverter/amplifi er of Fig. P2.34 let VCC 5 5 V, RB 5 10 kV, and RC 5 1.0 kV, and let the BJT have Is 5 1 fA, F 5 80, and VA 5 `. (a) Sketch and label the VTC for 0 # vI # 5 V. (b) Find the voltage VI needed to achieve VO 5 4 V. (c) What is the slope of the VTC at the operating point of part (b)?
