A couple of months ago, some guy with his own company approached my company with a circuit that consisted (he said) of 7 components (one op-amp, resistors and caps) that could improve linearization. We never got to see the circuit (He believed he could get rich on this...my company didn't bite). While we never had a black box from him, his simulations did show a large improvement in linearization. Normally we use a log amp that or just L/C matching (this is eddy-current sensing)to get some linearity, but depending on range/offset, we may end up with up to 10% non-linearity. Would anyone have any idea as to how he was configuring this circuit to linearize? Again, it was a single active component, an op-amp, with several passive components.
