The CE-ED amplifi er of Fig. P2.64 has an emitterdegeneration resistance of (15//0.1) kV. (a) If the BJT has F 5 125, VBE(on) 5 0.7 V, and VA 5 `, fi nd IC as well as the small-signal parameters Ri , Ro, and voyvi . (b) Find the equivalent resistance Req seen by C, and then specify C for operation at 100 Hz. (c) What happens if C is omitted altogether?
