A particular amplifier has a nonlinear transfercharacteristic that can be approximated as follows: (a) For small input signals, | vz| <5 mV, vo/vt = 10^3
(b) For intermediate input signals, 5 mV < | v, | <55 mV, Av()/Av, = 10^2.
(c) For large input signals, |vz| > 55 mV, the outputsaturates.
If the amplifier is connected in a negative-feedback loop, find the feedback factor ß that reduces the factor-of-10 change in gain (occurring at|v,) = 5 mV) to only a 10% change. What is the transfer characteristic v, versus vs of the amplifier with feedback?
