2.119 Consider the use of an op amp with a unity-gain frequency ft in the realization of:
(a) An inverting amplifier with dc gain of magnitude K.
(b) A noninverting amplifier with a dc gain of K.
In each case find the 3-dB frequency and the gain–bandwidth product (GBP ≡ |Gain| × f3dB). Comment on the results.
