Abstract
This work proposes a novel resistor- floating-re-
sistor-string digital-to-analog converter (RFR-DAC) architecture
with a 10-bit resolution for liquid crystal display (LCD) driver
applications. The proposed architecture improves the linearity
of DAC, uni fies its channel performance, and achieves a 10-bit
resolution with a compact die size smaller than those of the
state-of-the-art 10-bit DACs. The proposed RFR-DAC combines
a 6-bit RDAC and a 4-bit FR-DAC ( floating-resistor-string DAC)
to offer un
