AC parameters of an Op-amp results in reduction of output voltage
Q. Which of the following AC parameters of an Op-amp results in reduction of output voltage if it becomes excessive?- Published on 26 Oct 15a. Transient Response
b. Slew Rate
c. Bandwidth
d. All of the above
ANSWER: Bandwidth
The significant AC parameters of Op-amp are transient response, bandwidth and slew rate but all of them have different results while becoming excessive. The transient response affects the settling time while slew rate give rise to distortion if exceeded. As a result, bandwidth reduces the output voltage when it is exceeded.
Since bandwidth is a small signal phenomenon, it represents the band of frequencies for which the gain remains constant & also highly dependable on compensating components including closed loop gain. But, it exhibits adverse consequences in the reduction of an output voltage when exceeded to greater extent.
