Abstract

In this work, a simple, precise, physical parameters-based model of Amorphous-InGaZnO thin-film transistor is proposed by employing dominant attributes of the device in the specific operating region. The model precisely replicates the measured current–voltage characteristics of any long channel length TFT. In addition, the scope of the model is augmented to replicate the electrical behavior of short channel length TFTs by employing a basic approach that requires a few least-square empirical parameters. For a fixed short channel length TFT, an average error between model outcome and measured device response is found to be less than 3%. The unified model is incorporated in cadence simulator to simulate a 15-stage ring oscillator with long and short channel length TFTs. The simulation response is well accorded with expected device behavior, which further emphasizes the use of the proposed unified model to design oxide TFT-based circuits for a wide application range.
