Abstract: The invention relates to a method for conducting reference measurements of temperatures. A first pair (D1) of serially connected temperature resistor sensors (1) and (2) correlating with an associated temperature value of the resistor TCR but with asymmetrically different resistance values for Rvt1 and Rmt1 is simultaneously placed in measuring point (MB1) having measured temperature t1. The reference temperature tv is approximately the same as the expected temperature t0 of the measuring point (MB1) and preferably does not differ substantially from the measuring point (MB1). The pair (D3) of serially connected temperature independent resistors (5) and (6), whose resistance values Rv and Rm individually match is correlated with the values of the resistances rvt and Rmt of the first pair (D1) of temperature resistor sensors (1) and (2) preferably in but not too distant from measuring point (MB1). The first pair (D1) of temperature resistor sensors (1) and (2) is switched back-to-back with pair (D3) of the temperature independent resistors (5) and (4). The supply voltage Uin is applied to the external conductor (Vin+) and (Vin-) of both pairs (D1) and (D3) and between the external conductor (Vin-) and all resistors (1), (2), (5) and (6) and the common central conductor (Vout) commonly leading to the temperature independent resistor (6) having resistance value Rm.

Abstract: The thermal isolation of a thermally-trimmable resistor has a direct impact on temperature rise. It is possible to design the thermal isolation of the portions of a compound resistor to minimize or optimize the resistance variation of the overall compound resistor. The resistance variation of the overall compound resistor due to self-heating of its portions can be reduced or optimized, by designing different thermal isolation for each of the portions, such that compensation and/or optimization can occur. Furthermore, one can also design such different thermal isolation of the portions of a compound resistor to minimize resistance variation over a trim range of a compound resistor due to self-heating.
