Abstract: A temperature-determining device for determining a temperature (TMED) of a medium via a temperature of a surface includes: an ambient-temperature sensor, arranged in surroundings of the surface, for measuring an ambient temperature (TU); a surface-temperature sensor, lying on the surface, for measuring a mixed temperature (TM) lying between the temperature (TMED) of a medium and the ambient temperature (TU); and an arithmetic-logic unit having an approximation formula electronically stored thereon for calculating an approximation (TMEDN) of a temperature of a medium. The approximation formula is a sum of the mixed temperature (TM) and a product of two factors. The first factor results from a difference between the mixed temperature (TM) and the ambient temperature (TU) and the second factor results from a ratio of a dividend to a quotient. The dividend results from a difference between a calibration temperature (TMEDKAL) of a medium and a calibration mixed temperature (TMKAL).

Abstract: A temperature sensor having a two-state input current, an element whose temperature is sensed based on a change in voltage across the element induced by the two states of the input current, a charge-to-digital converter, and a capacitor continuously connected between the element and the charge-to-digital converter. The capacitor experiences a charge difference due to the change in voltage across the element induced by the two states of the input current, and the charge-to-digital converter converts the charge difference to a digital value indicative of the temperature of the element. A two-state DC-shifting current having opposite polarity of the two-state input current, a pull-down resistor whose voltage varies with the two-states of the DC-shifting current, and a second capacitor continuously connected between the pull-down resistor and the charge-to-digital converter operate to shift down a DC operating point of the charge-to-voltage converter to increase its dynamic range.
