温度传感器动态特性完全补偿方法研究与补偿电路设计
Research on Complete Compensation to Dynamic Characteristic of Temperature Sensor and Design of Compensating Circuit
摘要
Abstract
The first-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 similarity and intercommunity between the step responses of the two systems are pointed out, and then that the dynamic models of temperature sensor can be unified simplified as the first-order system model is put forward. The transfer function of compensating circuit which can make a first-order system to be compensated as a perfect all-pass system is derived. The active filter circuit which can realize the transfer function is designed, and the design formulas for calculating the circuit element parameters by thermal time constant of temperature sensor are given out. That the output voltage of signal conversion circuit are linear and proportionate to the sensor's temperature, and that compensating circuit and signal conversion circuit have sufficiently wide pass band, are pointed out as the two necessary conditions realizing complete compensation to dynamic characteristic of temperature sensor using hardwear.关键词
