- Abstract:
- The frst-order system model and second-order system model for dynamic characteristic of temperature sensor are analysed, The second-order system is not a underdamping system and that there are similarityand intercommunity belween the step responses of the two systems are pointed out, and then that the dynamicmodels of temperature sensor can be unifed simplified as the first-order system model is put forward, Thetransfer function of compensating circuit which can make a frst-order system to be compensated as a perfectall-pass system is derived. The active filter circuit which can realize the transfer function is designed, and thedesign formulas for calculating the circuit element parameters by therma! time constant of temperature sensorare given out. That the output voltage of signal conversion circuit are linear and proportionate to the sensor’stemperature, and that compensating circuit and signal conversion circuit have sufficiently wide pass band, arepointed out as the two necessary conditions realizing compleie compensation to dynamic characteristic of temperature sensor using hardwear.
