DC dual end power supplies?
I've seen how to make a dual power supply (in my case for an OP-amp) by grounding the centre of two batteries or cells, but where or what do you do on a real circuit, how would you ground a little DC circuit?
It is the same basic idea (as the battery example you used). Lets say your circuit needed a plus 5 volts and a -5 volts. You just could use two regulators a +5 volt one and a -5 volt one.
