Open loop bandwidth of an op-amp extend its bandwidth from
A. 0Hz to fo
B. 20dB to fo
C. 3dB to fo
D. 0.704dB to fo
Answer:A
Open loop bandwidth of an op-amp extend its bandwidth from
A. 0Hz to fo B. 20dB to fo C. 3dB to fo D. 0.704dB to fo
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?
