"Witryna22 maj 2024 · Any mismatch in gain between the two inputs will result in a degradation of CMRR. For optimum common-mode rejection, the undesired signal must be identical at the inputs to op amp 3. For high CMRR systems, resistor matching may need to be better than 0.01%. This is an expensive requirement if discrete resistors are used. " - Importance of cmrr
