Modeling the p-n junction i-u characteristic for an accurate calibration-free temperature measurement

The p-n junction i-u characteristic model is decisive for the accuracy enhancement of calibration-free temperature measurement. In this paper, we give a survey of adapted physically-based p-n junction i-u characteristic models, such as the Ebers-Moll₂ the Ebers-Moll₃ and the Gummel-Poon model. Furthermore, we build new models through polynomial extensions to the fundamental Shockey model. The considered models were investigated with regard to the application of calibration-free temperature measurement. Experimental results show a model improvement with both physically and mathematically-based models
