    how to remove the effect of thermal voltage completely from a logarithm opamp circuit :/ ??
    i am totally messed up with this , can't able to remove the effect to get the accurate log result.
    btw, i have connected diode as a feedback in inverting-opamp but the output is different from real log value.
