The present invention relates to the field of radio frequency identification, in particular to a temperature measurement and calibration circuit and a passive radio frequency identification tag. The slider tester, which tests reading and writing functions of a slider for reading data from and writing data on a recording medium, includes a testing device for testing the functions of the slider, and a setting plate holding the slider and electrically connecting the slider to the testing device. The fuzzy logic methodology incorporates a plurality of fuzzy logic control algorithms each having different membership functions and other control parameters that can provide different degrees of level control in the condenser. The first and second components solidify in the cavity to form the bar.
