D 12.4 An emitter follower using the circuit of Fig. 12.3,for which the output voltage range is ±5 V, is required usingVcc = 10 V. The circuit is to be designed such that the currentvariation in the emitter-follower transistor is no greater thana factor of 10, for load resistances as low as 100Q. What isthe value of R required? Find the incremental voltage gain ofthe resulting follower at vo = +5, 0, and -5 V, with a 100-Qload. What is the percentage change in gain over this rangeof v0?
