The cold-junction compensation is essential in temperature sensing using thermocouples. Every metal junction of different materials gives the thermo voltage. In the termocouple itself, but also where the thermo couple wires connect to the board a voltage is generated. The junction from the wires to the board is the so called cold-junction. The absolute temperature at this point has to be measured correctly to compensate the voltage developed here. The process of this compensation is the cold-junctioncompensation. This reference design shows different implementations for cold-junction compensation.The standard approach, using an RTD, is compared to different analog sensors, and integrated digital sensors. The design of a low-power front end for the thermocouple is also shown. The resulting performance of the different solutions are compared to each other. To compare different solutions, three boards are built using a different approach for CJC.
