The present paper Performance improvement in high speed low power out put 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. Post-layout simulations show that the proposed buffer can drive a 1000pF column line load with 8.5-V/μs slew-rate and 0.6-μs settling time, while drawing only 8-μA static current from a 1.2 -V power supply
