摘　　要：论述了一种采用热敏电阻电桥和高精密、低温飘、低功耗的运算放大器为微机控制OCXO设计测温电路的方法,并从多个角度对电路进行了深入透彻的分析。实验表明,这种测温电路结构简单、测温精度高、控温稳定性好。This paper designs a circuit of measuring temperature for OCXO with high stability. The circuit is made up of a NTCR electric bridge and an operation amplifier. The advantage of designed circuit is that it has a simple structure, and that it measures temperature accurately and controls temperature stably. Moreover, this paper also analyses the circuit thoroughly from many aspects.
