Explanation: In a non-inverting comparator a fixed reference voltage Vref of 1v is applied to positive inverting input terminal and the other time vary in signal voltage is applied to non-inverting input terminal of the op-amp. 4. How the op-amp comparator should be choosen to get higher speed of operation?
A. Large gain
B. High slew rate
C. Wider bandwidth
D. None of the mentioned
Answer:A
Explanation: In a non-inverting comparator a fixed reference voltage Vref of 1v is applied to positive inverting input terminal and the other time vary in signal voltage is applied to non-inverting input terminal of the op-amp. 4. How the op-amp comparator should be choosen to get higher speed of operation?
A. Large gain B. High slew rate C. Wider bandwidth D. None of the mentioned
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?
