5. A realistic amplifier can be modeled by the following non-linear transfer function. For this amplifier, the open- loop gain changes from 1000 to 100 for output voltage larger than 1 V. Find the feedback factor (B) to be used in the closed loop amplifier shown below such that, the closed loop gain varies only by 10%, when the output voltage is above and below 1V. What is the transfer characteristic of the resulting closed-loop feedback amplifier? Amplifier 1 a 1 V a 1-pa 10 10 out a Amplitier 1 R.
