Low-power and high-speed CMOS voltage buffer for flat panel displays

This paper proposes a very low-power and high-speed CMOS voltage buffer for column drivers of flat panel displays. The proposed amplifier circuit employs two complementary input stages and an improved output stage. The proposed circuit draws only 2μ quiescent current while a 1nF capacitive load is connected at the output. It has only a 0.82us settling time within a full-swing output. The simulations of the proposed circuit are performed using LTSpice with AMS 0.35μm process parameters and a single 3.3V power supply. It is shown that the circuit has the best Figure-of-Merit value when compared to the previously published solutions.ECTI Associatio
