Abstract: In this paper, we proposed a novel operational amplifier (op-amp) by using amorphous Indium-Gallium-Zinc-Oxide thin-film transistors (a-InGaZnO TFTs). The proposed op-amp is composed only with n-type TFTs, and can be fabricated within the area of . Through the simulation, the proposed op-amp is confirmed to have an open-loop voltage gain of 29dB at up to 2.6kHz when supply voltage is ¡¾15V. We expect the proposed a-InGaZnO TFT op-amp to be used in designing the power control and driving system for various display applications.
