I thought I had it sorted, I want to take a small input voltage (10mV-300mV) and amplify it 100x so I get 100mV-3V.
Simples I thought, a non inverting amplifier and off we go. I have some op amp reference circuits and like a muppet, I thought I would take a look through and see if there is anyway to do it with a single supply. What I was looking for, was a circuit I collected a couple of years ago, it used a op amp to create a negative supply, i cant remember much about it and never used it, I was then going to use this to drive the supply for another op amp to up the small imput voltage.
Well I have now utterly confused myself!
So any idea's how best to go about this? any hints would be great so I can untangle my brain again!
