What is the significance of CMRR slew rate and BW in op-amp operation?

What is the significance of CMRR slew rate and BW in op-amp operation?

It means, an ideal op-amp will amplify the signals of any frequency without any attenuation. Common Mode Rejection Ratio (CMRR) is infinity. Slew Rate (SR) is infinity. It means, the ideal op-amp will produce a change in the output instantly in response to an input step voltage.

What is the advantage of high CMRR in op-amp?

a high CMRR is good because it defines the difference at the output of an amplified differential mode input to an amplifier common mode input. Unwanted signals that couple into the differential input, predominantly will result in an unwanted common mode signal at the input.

What is CMRR What is the signification of CMRR list and explain the methods to improve the CMRR?

Answer: CMRR is the ratio of differential voltage gain (Ad) to the common mode voltage gain (Ac), so we can improve the CMRR by either increasing differential voltage gain or by decreasing common mode voltage gain. To increase CMRR, emitter resistance RE should be increased.

How does op amp increase CMRR value?

To increase the value of CMRR, which circuit is used to replace the emitter resistance Re in differential amplifier? Explanation: Constant current bias offers extremely large resistor under AC condition and thus provide high CMRR value.

What is CMRR define its values for an ideal and practical op amp?

CMRR stands for Common Mode Rejection Ratio. A typical value for CMRR would be 100 dB. In other words, if an op amp had both desired (i.e., differential) and common-mode signals at its input that were the same size, the common-mode signal would be 100 dB smaller than the desired signal at the output.
