Ideal vs. Nonideal Op Amps: Difference between revisions

Revision as of 00:44, 11 January 2010


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

- 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.
