CMRR of amplifier is to be calculated. Concept introduction: CMRR stands for Common Mode Rejection Ratio. It represents how effectively the common mode signal (for example -noise) is rejected by a difference amplifier. The formula to calculate CMRR is CMRR = A d A c where A d and A c represents difference mode and common mode gains of the difference amplifier respectively.

CMRR of amplifier is to be calculated.

Concept introduction:

CMRR stands for Common Mode Rejection Ratio. It represents how effectively the common mode signal (for example -noise) is rejected by a difference amplifier.

The formula to calculate CMRR is

CMRR=AdAc

where A_d and A_c represents difference mode and common mode gains of the difference amplifier respectively.
