An 8‐bit cascaded‐dividing DAC that can operate at a low power supply voltage is proposed. Occupying less than one eleventh of the chip area of a conventional binary‐weighted DAC with an equivalent resolution, the proposed DAC features a low operation voltage of 2 V with a good DNL and INL of less than 0.15 LSB. The proposed DAC is expected to be adequate for current‐driving AMOLED drivers that have very demanding requirements of a narrow channel pitch as well as high linearity and resolution for the data channel DACs.
