Abstract

An 8-bit LCD source driver with push-pull buffer amplifiers for N-dot inversion driving is presented. The proposed push-pull output buffer amplifier with dynamic bias effectively increases the transient response, reducing the transistor count of the bias circuit and decreasing the quiescent current path. An 8-bit source driver supporting an N-dot inversion driving scheme is implemented using 0.35μm CMOS technology. The developed driver has maximum setting times of 1.4μs and 1.2μs for rising and falling edges, respectively, under one-dot inversion with a 680pF load. The quiescent current consumption of the proposed push-pull buffer amplifier is about 3.8μA.
