Wanted: distortion free soft clipping circuit

[jan.didden]

I haven't worked through the whole design, but pos feedback issues can often be cured with a very little bit of hysteresis aound the loop.

@jan.didden, you are right that theory and practice deviate a lot.
In theory, the voltage across the op-amp inputs should be close to zero, in practice this is not the case at all.

The voltage between opamp inputs is always exactly Vout/Aol as long as it is in its linear range.
That means that it increases with frequency.
