I've been given this circuit and associated equations:
and this is the graph I should get, but I don't know how or why it looks like that, with g(x) as the current vs resistance. R3 and R6 are equations for resistors at the bottom of the schematic.
I assume that those two equations collide somehow and from that I get that g(x), but I'm not sure.
So my question is: How do I get that g(x) with that circuit?
I'm looking for High Stability Thermistors,this controller looks good: http://www.analogti.com/thermo-system-components/high-stability-thermistors.html. does anybody have experience in using that thermistors? Or are there better ones to recommend?
