IP5 - An Accurate Readout Circuit for Sensors Based on Thermopiles/Thermocouples

Qi Jia, Xiujun Li & Gerard C.M. Meijer
Thermopiles and thermocouples are commonly applied in a very wide range of applications, from contactless temperature measurement, infrared gas-absorption measurement, climate control to medical equipment and home appliances. When a conducting material is subject to a temperature gradience, the thermoelectric effect, or Seebeck effect, will generate a voltage difference between the hot and the cold end. Since this effect is material dependent, if two different types of material is connected at one end (for instance...
