(i) CMRR:- The CMRR is defined as the ratio of the powers of the differential gain over the common-mode gain, measured in positive decibels (thus using the 20 log rule): As differential gain should exceed common-mode gain, this will be a positive number, and the higher the better. 


CMRR= ADM/ACM



ii) Slew rate: The slew rate of an op amp or any amplifier circuit is the rate of change in the output voltage caused by a step change on the input. OR -The maximum rate at which an amplifier can respond to an abrupt change of input level It is measured as a voltage change in a given time.
