**You probably should cite "Characteristics of ideal amplifiers" written by Greg. I don't know if you need to site it since his hasn't been published yet. Looks good. It's always nice to see symbols used if possible instead of words where appropriate. I'm not sure where my comments are to go, but I think this is ready for publication. Maybe delete my comments later when you put your work in the "published" section. Not sure how the pints get awarded if you do that or if I do that. |

| Ideal | Nonideal |
|---|---|
| Infinite input impedance | Input impedance of about 1M Ω for IC op amps; as much as 10 12Ω for op amps with field effect transistor |
| Infinite open-loop gain for the differential signal | Open-loop gain typically between 104and 106 |
| Zero output impedance | Output impedance typically between 1 and 100 Ω |
| Infinite bandwidth | Bandwidth typically limited by the designer to avoid oscillation |
