Abstract

This study proposes a 10-bit two-stage DAC with an RDAC-embedded op-amp for TFT-LCD Column Driver IC. The 10-bit DACs are divided into positive 9-bit and negative 9-bit components to save the silicon die area. Each output channel combines a 6-bit two-voltage selector and a 3-bit RDAC-embedded op-amp in a cascaded manner. The 10-bit column driver prototype was realized in 0.18-pm CMOS technology with the worst DNL/INL being 0.29/0.72 LSB. The silicon area is only 11 × 373 μm2 for each output channel.
