Abstract

A high speed analog buffer using polycrystalline silicon (poly-Si) thin film transistors (TFT) is proposed for 2.2-inch quarter video graphic adapter (qVGA) TFT-LCD panel. Simulation results show that the settling time of the proposed circuit is $10{\mu}sec$ in 2.2-inch qVGA and the power consumption of proposed analog buffer is $25{\mu}W$.
