Ideal vs. Nonideal Op Amps
From Class Wiki
Ideal | Nonideal |
---|---|
Infinite input impedance | Input impedance of about 1M Î© for IC op amps; as much as 10 ^{12}Î© for op amps with field effect transistor |
Infinite open-loop gain for the differential signal | Open-loop gain typically between 10^{4}and 10^{6} |
Zero output impedance | Output impedance typically between 1 and 100 Î© |
Infinite bandwidth | Bandwidth typically limited by the designer to avoid oscillation |
