Clipping a Universal op-amp


 

The internal representation of the level.2 op-amp ("UniversalOpamps2.sub" ?) does not seem to use actual transistors, presumably for speed of simulation and to make it more generic. What external parts are best to make output-level clipping work more like a 'real' opamp?

In the file "test_o1.asc" are two sets of two circuits.

Limiting the output swing with a diode does not speed up recovery in the first set.
?
The second set uses a 'real' op-amp, and gives a result more like I hoped.

P.S.
Incidentally - Is there a nicer way of doing this than diode limiting? Is there some (perhaps non-linear) circuit (Vbe of bipolar etc) that looks at the error voltage and reacts when it exceeds say 100mV ?
