Hi Joerg,
you appear to have full control over the math and the comments I make
are made without any real calculations to back it up, so this might
be irrelevant. :-)
Ok, the point I was trying to raise is:
Wouldn't it be possible to treat the virtual ground purely as a
reference signal without any capacitances loading it down at all? If
the amplifiers were treated as single-supply amps, then they would
only be decoupled across V+/V- without involving virtual ground.
Consequently, the capacitive loading of the virtual ground amplifier
could be reduced to strays only and perhaps the ringing you
experience would cease?
Just a thought...
Regards,
Andreas
