Be sure to clearly state any assumptions made on solving problems and clearly specify which process or model parameters you use. All problems are weighted equally. Problem 1 A feedback amplifier is shown below in which the standard op amp has been replaced with a transresistance amplifier of gain R T . a) If R 2 =500K and R 1 =100K, determine the voltage gain IN OUT V V V A = if R T is arbitrarily large. b) How large must R T be so that the actual gain does not differ by more than 1% from the value obtained in part a)?...
