I explained earlier in this thread that feedback does not affect slew distortion, neither positively nor negatively.
When I speak of op amps I mean what's inside them. Whether this circuit is executed using discretes or on a chip has no import on how the circuit is analysed. Most discrete amplifier circuits are op amps too.
Depending on the amount of abstraction, an op amp has several possible definitions.
1) (schoolbook) a circuit with two inputs and one output. The output voltage is plus infinity times the voltage difference between the inputs. Actual output in a given circuit is arrived at through limit calculus.
2) (practice) a circuit with two inputs, one output and a output reference (usually one of the supply rails, sometimes ground). The output voltage is the time integral of the voltage difference across the input times the gain-bandwidth (expressed in radians/sec), referenced to the output reference.
According to the first definition, an op amp is a P controller with P tending towards infinity. According to the second definition, an op amp is an I controller with I equal to the gain bandwidth product (in rad/sec).
There is also a third "definition" which is more like a recipe:
3) An op amp is a transconductance amplifier followed by a transimpedance amplifier, where the transimpedance of the latter is substantially capacitive.
In most op amps (be they integrated circuits or discrete circuits) there is no "corrective circuitry" other than the gain of the amplifier itself. In circuits employing local feedback loops, these loops are faster than the main loop as a matter of course, or the whole shebang simply wouldn't work at all. No op amp using "corrective circuitry" that is *not* stable would even make it off the lab table.
If the need arises (and when I have more time) I'll put up some op amp theory here.
All too often, I read blurbs (sales literature) suggesting that "stability" and "correction" and what have you are "difficult" and so on. I should warn against the hijacking of technical terms to be used by sales people who charge them with emotions.
It seems that what "the terrorist" is to politics, negative feedback is to audio. Something to be vilified, stereotyped and used to make anything acceptable by.
