Yes, I know. I have already uploaded such a
schematic
example using one a few years go. It doesn't explicitly show
crossover distortion, though - just the residual.

To evaluate
and quantize crossover distortion you can use a notch filter
(RC bridge) to eliminate the fundamental frequency out of the
output voltage.
I have uploaded an
example schematic
featuring the Quad 303 output stage.

You can also do this with a .DC
analysis. With this it's also very easy to do a
"wingspread" plot, which plots the incremental gain, which
is very revealing.

1.Use.TRAN analysis, not .AC,
because that doesn't show non-linearity.
2. Check that the current through
the output devices is very small with no input
signal.

If I build a Class B amplifier (all have cross
over distortion) What do I have to do, to see cross
over in a trace...
All I get is a perfect looking sign wave... What
would be the analysis and steps to do this...??
Any thoughts on this would certainly be
appreciated..... Thanks....
