Figure 4 shows the ac equivalent circuit of an emitter follower. (a) The transistor parameters are ß = 120 and VA=∞. For RE = 50092, determine Ico such that the small-signal voltage gain is Av = 0.92. (b) Using the results of part (a), determine the voltage gain if VA = 20 V. (c) Determine the small-signal output resistance R, for both parts (a) and (b). Rib vot RE Figure 4 shows the ac equivalent circuit of an emitter follower.
