2.5 Refer to Exercise 2.3. This problem explores an alternative internal structure for the op amp. In particular, we wish to model the internal structure of a particular op amp using two transconductance amplifiers and one transresistance amplifier. Suggest an appropriate topology. For equal transconductances Gm and a transresistance Rm, find an expression for the open-loop gain A. For Gm = 100 mA/V and Rm = 1 × 105 Ω, what value of A results?
104 V/V
