D 12.4 An emitter follower using the circuit of Fig. 12.3, for which the output voltage range is ±5 V, is required using VCC = 10 V. The circuit is to be designed such that the current variation in the emitter-follower transistor is no greater than a factor of 10, for load resistances as low as 100Ω. What is the value of R required? Find the incremental voltage gain of the resulting follower at vO = +5, 0, and –5 V, with a 100-Ω load. What is the percentage change in gain over this range of vO? R = 152Ω; Av = 0.998,0.996,0.978 V/V; 2%
