Abstract

A 10 bit digital-to-analog converter (DAC) with an interpolating buffer amplifier is proposed for AMLCD column drivers. The proposed circuit is more effective than a conventional circuit in decreasing the DAC (Pass-Transistor Logic) area per channel. The average static current per channel is 1.8 μA and the average interpolating error rate in most of the gray range is a sufficiently small rate of 2.5 % (and less than 0.5 % in the mid-gray range). The uniformity of the channel output is also guaranteed by the proposed error-reduction technique.
