Abstract :
Analytical drain current expressions with self-heating effect are presented for undoped polycrystalline thin film transistors (poly-Si TFTs). Temperature dependence of threshold voltage and effective mobility is involved. The expressions are derived on the basis of a first order Taylor expansion and continuous from linear regime to saturation regime. The validity of this model is verified by available experimental data and a good agreement is obtained.
