Abstract

We have developed a low-power, high slew-rate OP-AMP for large size and high resolution TFT-LCDs which have 8${\mu}$A quiescent current with settling time less than 6${\mu}$sec. The proposed OP-AMP contains newly developed the driving circuit of class-AB output stage which can achieve a low quiescent current less than 8${\mu}$A and a slew-rate higher than 3.14V/${\mu}$sec.
