This paper presents 8-bit differential output of hybrid Digital-to-Analog Converter (DAC) with rail-to-rail buffer using Silterra 0.18 µm CMOS process technology for mixed-signal application. The proposed design combines binary-weighted resistor and thermometer coding, which is able to enhance the speed of the data converter by implementing a small die size area as compared to the conventional architecture. The design achieved standard accuracy of 8-bit resolution with INL and DNL of ±0.5LSB and ±0.7LSB, respectively, and overall power consumption of 56 mW. The performance is accomplished with an effective design area of 133 µm × 172 µm. |
