Enter the differential gain and the common mode gain into the Calculator. The calculator will evaluate the CMRR (common mode rejection ratio).

## CMRR (common mode rejection ratio) Formula

CMRR = Adiff/Acom

Variables:

- CMRR is the CMRR (common mode rejection ratio) ()
- Adiff is the differential gain
- Acom is the common mode gain

To calculate CMRR (common mode rejection ratio), divide the differential gain by the common mode gain.

## How to Calculate CMRR (common mode rejection ratio)?

The following steps outline how to calculate the CMRR (common mode rejection ratio).

- First, determine the differential gain.
- Next, determine the common mode gain.
- Next, gather the formula from above = CMRR = Adiff/Acom.
- Finally, calculate the CMRR (common mode rejection ratio).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

differential gain = 7.2

common mode gain = 8.9
