Explanation: The gain of the op-amp remains essentially constant from 0 to the break frequency fo and therefore rolls off at a constant rate of 20dB per decade. Thus, the open-loop bandwidth is the frequency band extending from 0Hz to fo. 2. What happens if 741 op-amp is configured as a closed loop inverting amplifier?
A. Gain increases
B. Gain roll-off at a rate 20dB/decade
C. No gain roll-off takes place
D. Gain decreases
Answer:A

A. Gain increases B. Gain roll-off at a rate 20dB/decade C. No gain roll-off takes place D. Gain decreases
Explanation: Whether the op-amp is inverting / non-inverting the gain will always roll-off at a rate of 20dB/decade, using only resistive components regardless of the value of its closed loop gain. 3. Op-amp requiring external compensating components is called as
