| 摘 要： | 为了提高温度测量的精度,提出一种应用时间数字转化技术(Time-to-Digital Converter,TDC)测量时间间隔从而测得温度的方法。对RC电路充、放电,将温度数值的改变量转化为对时间间隔长度的数值采集,应用TDC进行时间间隔测量以提高其温度测量精确度。仿真实验显示,使用TDC技术能将温度测量精度提高到(0.020±0.004)℃,说明该技术对温度测量具有高精度、低功耗的优势。

| Abstract: | In order to improve the accuracy of temperature measurement,a kind of Time-to-Digital conversion（TDC） technology is introduced,by which,the temperature can be got from measurement of the time intervals.In other words,the change value of the temperature can be converted into some time intervals when the Resistance-Capacitance（RC） circuit is charged or discharged.Simulation results shows that,the temperature measurement accuracy will be incresed by（0.020±0.004）℃ when TDC is used.Temperature measurement with this technology is of higher accuracy and lower power consumption. |
