Definition:- i) SVRR: It is defined as the ratio of change of input offset voltage to the change in one supply voltage while keeping other supply voltage constant. Ideally,SVRR=0

ii)CMMR:-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.
