The Boltzmann constant Multisim simulation test
LI Ming-biao
Abstract：In this paper , Multisim simulation software is used to build the virtual simulation experiment cir-cuit, and the scheme of Multisim simulation experiment and the method of parameter setting are given .The dif-fused current of PN junction varies exponentially with voltage , which is the physical characteristics of PN junction and the experimental principle of the Boltzmann constant .The experiment is in accordance with FD -PN-2 model given by the PN junction physical properties determination instrument experiment circuit and component model.The virtual simulation experiment circuit and the experiment process are easy to understand and help to raise the experimental level and the teaching effect .In the simulation experiment , the voltage on the emitter of the triode is changed by adjusting the resistance , so that the output voltage is changed .The experimental data are analyzed by linear function , power function and exponential function .Comparing standard deviation and cor-relation coefficient , the fitting curve is exponential curve .At room temperature , the calculated Boltzmann con-stant is quite close to the experimental values .The test circuit of the simulation experiment is simple , the experi-ment process is clear and intuitive , the voltage regulation is convenient , and the data calculation result is more accurate .The simulation experiment will help students create a good simulation environment , and improve the experimental level and teaching effect
