Abstract :
A low voltage 10 bit DC DAC is fabricated in a standard 0.18 μm CMOS process. The DAC is optimized for circuit calibration in large ASICs and occupies 0.01034 mm2 (110 μm×94 μm) of die area. Creative layout and current mirroring techniques are implemented to minimize area while providing output current with sufficient headroom. The measured DNL/INL is better than 0.7/0.75 LSB and 0.8/2 LSB for 1.8 V and 1.4 V power supplies, respectively. The DAC consumes 3.96 mW at 1.8 V and 3.08 mW at 1.4 V.
