Hi Everyone,
I'm having trouble designing an opamp circuit that does a 2:1 amplification of a 140Hz sinusoidal signal +-0->1V without a ground plane. Does anyone know a simple method of doing this without specifying a reference plane?
If possible, I'd like to do this with just some resistors a battery bank (3AAAs = ~4.5V) and a single opamp.
Thanks!
(If I add in a 5V regulator and up the battery bank to 5AAAs to power it, can I use the regulators ground as the ground plane?)
