In an ideal op amp the open loop gain is 10 3. Output impedance z out output impedance is defined as the ratio of the output voltage to the input current. Which concept states that if one input terminal of an op amp is at zero potential then the other one also will be at zero potential.
Cmrr of a differential amplifier can be improved by decreasing a differential voltage gain.
That is there no current flowing in the input circuit. It is another way to refer to op amps based on its terminal characteristics.
