Resumo

This paper addresses a very compact low-power class-B buffer amplifier topology for large-size liquid crystal display applications. With enhanced slew rate, Edge-Detecting technique the proposed buffer achieves high-speed driving performance, draws a small quiescent current during static operation. The proposed SRE design is achieved more than 68 times improvements in the slew rate without significant increase of static power dissipation. Post-layout simulations show that the proposed buffer can drive a 20-pF column line load within 1.8-s settling time under a full voltage swing, while drawing only 4.1 ðœ‡A static current from power supply. Keywords: Analog integrated circuit, current-mirror amplifier, slew rate (SR), slew-rate enhancement (SRE) circuit
