    Hi not really wanting an answer but more a method to work this one out. How do you calculate the CMRR for an op-amp with a difference voltage of Vd = 1mV, difference output Vo = 120 mV, common voltage Vc = 1mV, common output Vo = 20 microAmps?

    Many thanks

    CMRR = | differential gain / common mode gain |
