1. The problem statement, all variables and given/known data I'm trying to calculate what voltage change will compensate for a temperature change of 1 degree for a diode. I have set up the circuit, taken down results and plotted the graph (its non-linear). So I re-plotted it using natural logs of I, and got a straight line with a gradient. Now I'm lost as to how to answer this question. 2. Relevant equations I= Is x (e^(eV/kT) -1) It's the characteristic equation for V vs I for a diode. 3. The attempt at a solution I took natural logs to get: ln I = lnIs x (eV/kT - 0) Then said the gradient is equal to e/kt. But then where do I go from there? A little push in the right direction would be great! Thanks in Advance!
