PN JUNCTION（DIODE） TEMPERATURE SENSOR PERFORMANCE EXPERIMENTAL SYUDY
ABSTRACT
Here this topic is to obtain experiment data through measurement of different type's PN semiconductors on the forward voltage drop and the temperature characteristic survey. To organize, analysis and synthesize experimental result to get temperature characteristic conclusion of each different type semiconductor PN component and then to research and study the different semiconductor materials, different semiconductor PN to tie the component, develops its forward loss of voltage and the temperature relations characteristic survey separately tests and studies, compares various components sensitivity, the linearity fit and unfit quality. Mainly analysis the different model diode's temperature characteristic identical kind of model 3 diode's temperature characteristic analysis identical kind of model diode's under different constant current temperature characteristic identical diode multiple metering temperature characteristic, to select the PN junction temperature sensor to provide the choice basis reasonably. And the major type includes 2CP11, 1N4007 diodes,2CW117 diode , 2CN2 diode and S9014 dynatron which used for control experiment.
Key words: PN junction; temperature sensor; linearity
