As the display resolution increases, the load capacitance of buffer amplifier increases, whereas the required settling time decreases. The paper performance improvement in high speed low power output Buffer amplifier for large - LCD applications. The proposed buffer achieves high-speed driving performance while drawing a low quiescent current during static operation. The circuit offers enhanced slewing capabilities with limited power consumption by exploiting a slew detector which monitors the output voltage of the input differential amplifier and outputs an additional current signal providing slew-rate enhancement at the output stage.
