Which of the following is a combination of inverting and non-inverting amplifier?
(a) Differential amplifier with one op-amp
(b) Differential amplifier with two op-amps
(c) Differential amplifier with three op-amps
(d) Differential amplifier with four op-amps
This question was posed to me by my college professor while I was bunking the class.
My question comes from Differential Amplifiers with Multiple Op-Amp topic in division Operational Amplifier Characteristics of Linear Integrated Circuits
