Abstrakt: Considered problems of instability of iterative processes in the analysis of I/V measuring converters with negative differential resistance caused by self-heating of these converters. An express method of determining the limits in which correct electrothermal DC analysis is provided has been developed. A method of synthesis of electrothermal models of thermoresistive, diode and transistor structures of primary converters of thermal flow sensors is proposed. In contrast to well-known circuit modeling packages (PSpice or MicroCAP), the proposed method allows you to obtain I-V characteristics in one cycle of DC analysis, taking into account the self-heating of the above-mentioned converters. The developed differential thermometer is a universal device for measuring the temperature difference, in particular for the implementation of thermal flow sensors, means of biochemical analysis, thermal conductivity, etc., and is characterized by a temperature difference measurement resolution of no worse than 0.001°C.
