In the circuit of let VEE 5 2VCC 5 5 V, RC1 5 RC2 5 12 kV, IEE 5 0.6 mA, and REE 5 `. (a) Assuming ro 5 `, fi nd the gain a. Find vod if vI1 5 (8 mV) cost and vI2 5 0. (b) Assuming negligible base currents, fi nd the total voltages vO1 and vO2 (express each voltage as the sum of its dc and ac components). (c) Find vod if a 30-kV load is connected between the two collectors. (d) Find the total signals vO1, vO2, and vOD if RC2 is accidentally lowered to 10 kV. Comment on your results.
