The purpose of level shifter in Op-amp internal circuit is to
A. Adjust DC voltage
B. Increase impedance
C. Provide high gain
D. Decrease input resistance
Answer:A
The purpose of level shifter in Op-amp internal circuit is to
A. Adjust DC voltage B. Increase impedance C. Provide high gain D. Decrease input resistance
Explanation: The gain stages in Op-amp are direct coupled. So, level shifter is used for adjustment of DC level.
