• Constant Mode Rejection Ratio (CMRR)of a differential amplifieris the rejection by the device of unwanted input signals common to both inputs.

• CMRR is the ratio of differential gain to the common mode gain.

• Methods to improve CMRR in Differential Amplifier:

  I. Use of constant current bias

  i. Following figure shows …
