“…Modern transistors are characterized by extremely small size (from millimeters to micrometers), and temperature sensors based on them, provide significantly higher temperature sensitivity compared with resistance temperature detectors (RTDs) or thermocouples [2]. In addition, the use of transistors opens up the possibility of expanding functionality, in particular, providing both temperature measurement and controlled heating [4,5].…”

The analysis of the nonlinearity of the transfer function of primary temperature transducers based on transistor structures has been performed. It’s shown that the quadratic component of the transfer function creates a significant nonlinearity error up to 0,2-0,6°C. We have developed methods of linearization based on both the formation of compensatory measuring current and change of the conversion factor of the output scaling amplifier at certain ranges of temperature measurement, which ensure their use in precision temperature measuring devices. The measurement error does not exceed 0.01°C in the range of 30-100°C.

“…In accordance with current trends in the development of sensor electronics, the use of RETwix has significant relevance in the concept of Data fusion and Sensor fusion [14]. In this concept, we have implemented integrated devices for combining thermal measurement methods with capacitive [2], magnetic [4] and optical [3] sensors. Such integrated devices are the basis of IoT sensors for chemical and biological analysis in the concept of Lab-on-Chip.…”

“…Various measures and methods are applied to improve the accuracy of measurements in a wide range: stable materials and calibration are used, systematic errors are corrected, linearization measures are carried out, sensitivity is increased, and so on. Thus, in [4], an increase in sensitivity was achieved using low-current base-collector voltage, and in [5] elements of solid microelectronics and multifunctional signal converters based on calorimetric methods were used. Ways to increase the speed of transistors based on materials science structures and schematic aspects of selectively doped heterotransistors are given in [6].…”

The research of the systems of equations of quantities describing, respectively, 5 and 6 measurement cycles revealed the peculiarities of redundancy formation. It is proved that the normalized temperature T1 has the greatest effect on the measurement result for both systems. In addition, it was found that in both systems, an increase in the reproduction accuracy of the normalized temperature T1 (with a constant reproduction error of T2) does not lead to a significant improvement in the results. Due to this, it can be argued on the use of non-precision normalized sources to reproduce the temperature T1. However, an order of magnitude increase in the reproduction accuracy of both normalized quantities T1 and T2 also increases the measurement accuracy by an order of magnitude. Computer modeling confirmed that for the redundant measurement equation (11) at the ratio Т1=Ті(0.0005•Ті+1) in the range (10÷200) °С, measurement with a relative error (0.01÷0.00003) % is provided. When applying the redundant measurement equation (13), the accuracy increases to 0.0059 % only at the end of the range. Based on the results obtained, it was found that the accuracy of redundant measurements is influenced by the type of equation itself, not their number. Processing of the results based on the redundant measurement equation, by the way, ensures the independence of the measurement result from the influence of absolute values of the transformation function parameters, as well as their deviations from nominal values under the influence of external destabilizing factors. Thus, there is reason to believe that it is possible to increase the accuracy of measurement in a wide range by observing the ratio between normalized and controlled quantities
