How to Calculate Common-mode rejection ratio of the difference amplifiers?
Common-mode rejection ratio of the difference amplifiers calculator uses CMRR=20*log(modulus(Differential mode gain)/modulus(Common Mode Gain),10) to calculate the CMRR, The Common-mode rejection ratio of the difference amplifiers indicates how much of the common-mode signal will appear in your measurement. . CMRR and is denoted by CMRR symbol.
How to calculate Common-mode rejection ratio of the difference amplifiers using this online calculator? To use this online calculator for Common-mode rejection ratio of the difference amplifiers, enter Differential mode gain (Ad) and Common Mode Gain (Acm) and hit the calculate button. Here is how the Common-mode rejection ratio of the difference amplifiers calculation can be explained with given input values -> 20 = 20*log(modulus(100)/modulus(10),10).
