A low-power, high-speed, but with a large input dynamic range and output swing class-AB output buffer circuit, which is suitable for flat-panel display application, is proposed. The circuit employs an elegant comparator to sense the transients of the input to turn on charging/discharging transistors, thus draws little current during static, but has an improved driving capability during transients. It is demonstrated in a 0.6 /spl mu/m CMOS technology.
