D 7.84 An emitter follower is required to deliver a 0.5-V peak sinusoid to a 2- kΩ load. If the peak amplitude of vbe is to be limited to 5 mV, what is the lowest value of IE at which the BJT can be biased? At this bias current, what are the maximum and minimum currents that the BJT will be conducting (at the positive and negative peaks of the output sine wave)? If the resistance of the signal source is 200 kΩ, what value of Gv is obtained? Thus determine the required amplitude of vsig. Assume β = 100.
