Abstract

The design of a compact low-power high-speed class-AB buffer amplifier for driving the large column line loads of large-size TFT-LCD is presented in this paper. The class-AB buffer amplifier can drive large column line loads up to 1000pF within 1.28μs. The proposed class-AB buffer amplifier is implemented with a standard 0.35μm CMOS 2-poly 4-metal process technology and simulated using HSPICE. The measurement results show that the power consumption of 25.67μW, and exhibits the slew rates of 4.5V/μs and 5V/μs for rising and falling edges, respectively, under a 1000pF load. The active area of this class-AB output buffer amplifier is only 47×45μm2.
