摘要
This brief presents a novel approach to modeling gate bias-induced threshold-voltage (V-th) degradation in hydrogenated amorphous silicon thin-film transistors (TFTs). The V-th degradation model is added to the SPICE 3.0 TFT device model to obtain a composite model and is verified by comparing the simulated Vth shift with measured data in a TFT latch circuit.
