A. It require large value of R and small value of C
B. It require large value of C and small value of R
C. It require large value of R and C
D. It require small value of R and C
Answer:A
Where C-> Integration constant and CF-> Feedback capacitor. 3. Why an integrator cannot be made using low pass RC circuit?
A. It require large value of R and small value of C B. It require large value of C and small value of R C. It require large value of R and C D. It require small value of R and C
Explanation: A simple low pass RC circuit can work as an integrator when time constant is very large, which require large value of R and C. Due to practical limitations , the R and C cannot be made infinitely large. 4. How a perfect integration is achieved in op-amp?
