由硅材料电阻率的选择、结面积设计的不同，试制几种温敏二极管，在恒定电流下，测量室温至１２０℃温度范围内正向电压Ｖｆ与温度Ｔ的关系，测试结果表明，Ｖｆ－Ｔ特性曲线线性优良，在恒定电流为５０μＡ下，灵敏度最高的可达２．７０ｍＶ／℃．根据测试结果，对提高灵敏度等特性进行一些讨论． According to the choice of resistivity of silicon material and the design of junction area, several kinds of temperature-sensitive diodes are manufactured. Under constant current, the relationship between the forward voltage Vf and temperature T is measured. The test results show that Vf- The T characteristic curve has excellent linearity with a maximum sensitivity of 2.70mV / ° C at a constant current of 50μA. According to the test results, to improve the sensitivity and other characteristics of some discussion.
