    Adaptation of a compact SPICE level 3 model for oxide thin-film transistors
    (Springer, 2019-05) Gupta, Navneet; Kandpal, Kavindra
    Oxide thin-film transistors (TFTs) and metal–oxide–semiconductor field-effect transistors (MOSFETs) operate via different conduction mechanisms but exhibit similar device characteristics. In this work, a SPICE level 3 model originally defined for MOSFETs is successfully adapted to provide a behavioral model for oxide TFTs. This adapted compact model is applicable to all kinds of oxide TFTs, irrespective of the channel and dielectric material used. To capture the TFT behavior efficiently, the experimental characteristic of an oxide TFT is used to set various SPICE level 3 parameters.
