Explanation: The bandwidth of the op-amp comparator must be wider so that the output of comparator can switch rapidly between saturation levels. Also, the op-amp responds instantly to any change in condition at the input. 5. How to obtain high rate of accuracy in comparator?
A. All of the mentioned
B. High voltage gain
C. High CMRR
D. Input offset
Answer:A
Explanation: The bandwidth of the op-amp comparator must be wider so that the output of comparator can switch rapidly between saturation levels. Also, the op-amp responds instantly to any change in condition at the input. 5. How to obtain high rate of accuracy in comparator?
A. All of the mentioned B. High voltage gain C. High CMRR D. Input offset
Explanation: High voltage gain causes comparator output voltage to switch between saturation levels. High CMRR rejects noise at input terminal and input offset (voltage & current) help to keep changes in temperature variation very slight. 6. How to keep the output voltage swing of the op-amp comparator within specific limits?
