Abstract : An uncomplicated and reliable temperature sensor has a pair thermistors coupled in parallel with a current source that is connected in series with a load resistor. Temperature variations cause a robust current output change that generates a corresponding robust output voltage determined by a proper selection of the load resistor. Increased sensitivity is provided by the robust current to avoid many of the problems otherwise associated with D.C. amplifiers (e.g., drift).
