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
Answer:A
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
Explanation: In differential amplifier with one op-amp both the inputs are connected to separate voltage source. So, if any one of the source is reduced to zero, differential amplifier acts as an inverting or non-inverting amplifier.
