Abstract

In this paper, we presented a low-dropout (LDO) regulator composed with amorphous indium-gallium-zinc-oxide thin-film transistors (a-InGaZnO TFTs) for display driving systems. Through extensive simulation works, we confirmed that the proposed LDO regulator successfully could control the output voltage levels to follow the reference input voltages, and the output voltage ripple could be suppressed below 48mV when input reference voltage was changed from 14V to 15V with 100mV fluctuation.
