I am wondering what is the difference between them as shown in attachment. Can any one please explain ? Attachments Untitled_10.png 36.5 KB · Views: 119

CMRR is the ratio of common-mode gain to differential gain. PSRR is the ratio of power supply change to output change CMVR is the common-mode voltage range of the opamp input
