Hello all.
I've been experimenting with all sorts of opamp circuits. I was
wondering what would be the best way to get a + and - rail from a
battery. I was thinking that I could use a voltage divider with
resistors, but I don't think this method is very efficient.
Could someone point me towards some info about this matter?
Thanks!

You can add capacitors in parallel for better AC stability of the ground.
Actively driving the ground with an opamp is another way.
