半导体温度传感器1原理半导体PN结测温技术是近年来发展起来的一种测温手段。众所周知，PN结的反向电流随温度呈指数规律变化，而当正向电流不变时，PN结的正向压降随温度近似线性变化。现代的PN给温度传感器都利用正向压降进行测温。PN给温度传感器线路如图1所示，PN结的正向
Semiconductor temperature sensor 1 Principle Semiconductor PN junction temperature measurement technology developed in recent years is a means of temperature measurement. As we all know, PN junction reverse current changes exponentially with temperature, and when the forward current is constant, PN junction forward voltage drop with the temperature changes approximately linearly. Modern PN temperature sensors use positive voltage drop for temperature measurement. PN to the temperature sensor circuit shown in Figure 1, PN junction forward
