Unity gain/voltage follower question...

[ExpAnonColin]

So where does the Vbias go?  There's nothing grounded on a voltage follower, just the V- and V+ of the op amp, so how do I trick the op amp into using the ground?  Can I just do ground and not worry about a vbias or is there another special trick?

Followers don't use Vbias, unless the follower is AC coupled in which case a Vbias of high impedance is connected to the signal input.

Take care,

Colin, look at the way the opamp buffers are configured in my article at:
