Explanation: In practice, the output of op-amp never becomes infinite rather the output of the op-amp saturate at a voltage close to op-amp positive or negative power supply depending on the polarity of the input dc signal. 6. The frequency at which gain is 0db for integrator is
A. f=1/(2πRFCF)
B. f=1/(2πR1CF)
C. f=1/(2πR1R1)
D. f=(1/2π)×(RF/R1)
Answer:A
