摘要

A short rise time, short fall time, and small ripple are required to reduce the misoperation of pixel data voltage and to improve the stable signal processing of a driver circuit. In this study, a novel amorphous silicon gate (ASG) driver circuit consisting of 15 hydrogenated amorphous silicon thin-?lm transistors (a-Si:H TFTs) and two capacitors was optimized using a thin-film transistor (TFT)-circuit-simulation-based multi-objective evolutionary algorithm on the unified optimization framework . The ASG circuit was optimized for the following given specifications: rise time 0.7?μs; fall time 0.6?μs; ripple peak 6.5?V; clock Ctotal 40?pf; and total TFT widths 6000?μm. The main findings of this study show that the rise time had an 18% reduction and that the fall time, total widths, and clock Ctotal had 7, 17.5, and 9% reductions, respectively.
