Indeed Alex.

If the device output current is defined as I0 + k1v + k2v.exp2 + k3v.exp3 etc
where I0 is the dc, v is the input volts and k1, k2, k3 etc are the 
coefficients of the transfer function

Then using coefficients for a 3/2 law and comparing the results against using 
coefficients for a logarithmic law shows very strongly the differences in the 
higher order products, with the log law being far worse. Even with NFB.

It sums up as 'you can't win, but you may be able to lose less badly!'
