The present paper addresses an improved low-power high-speed buffer amplifier topology for large-size liquid crystal display 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 a 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 1 nF column line load with 8.5 V/μs slew-rate and 0.8 μs settling time, while drawing only 8 μA static current from a 3 V power supply.
