Using the real amplifier outlined in Problem 2, how would you change the input/output resistance of the amplifier so as to maximize the real gain?
Problem 2
The (open-loop) gain of an amplifier which has an input/output resistance of 105 Ω/103 Ω is given as 104. If a transducer which has an internal resistance of 100 kΩ and produces a 10 µV signal is connected to the input of the amplifier, find the real gain of the amplifier when a load of 1 kΩ is connected to the output of the amplifier.
