7.58 The transistor in the circuit shown in Fig. P7.58 is biased to operate in the active mode. Assuming that β is very large, find the collector bias current IC. Replace the transistor with the small-signal equivalent-circuit model of Fig. 7.26(b) (remember to replace the dc power supply with a short circuit). Analyze the resulting amplifier equivalent circuit to show that Find the values of these voltage gains (for α  1). Now, if the terminal labeled v o1 is connected to ground, what does the voltage gain vo2/vi become?
