摘要

A high slew-rate low power CMOS buffer amplifier for high resolution TFT-LCD column drivers is proposed. Low power and high driving capability are achieved by using a telescope-cascode based complementary differential input stage combing with a common-source push-pull stage and two auxiliary driving transistors. The buffer amplifier attained 20 V/μs and 18 V/μs rising/falling slew rates, 0.96 μA static current, and 2.2 mV offset voltage for 1 nF load capacitance. It is effective for a high speed and high resolution TFT-LCD driver.
