Solving an Op Amp Circuit with Mathematica

[QUOTE="berkeman, post: 6191700, member: 8921"] Hmm, I'd have to write the equations to be sure, but I would think that the sensitivity is monotonic with respect to the feedback resistor values. Increasing the feedback resistance should increase the gain of the bridge output circuit, so it seems more likely that the limiting equation would come from the opamp railing out. For that, we'd need to know the maximum temperature range that is desired to measure, and then that gives us the extremes of the Rs values, which would then constrain the max value of Rs. And to get close to full rail-to-rail output on the opamp, it would need to be a fairly high quality FET model. (I know they are assuming an ideal opamp in this problem) [/QUOTE]
