摘要

This paper presents design of an 8-bit 1.8 V segmented current steering (CS) digital-to-analog converter (DAC) using 0.18 mum double poly five metal CMOS technology. The DAC has been segmented as 6+2 to achieve optimum performance for minimum area. The simulation result shows a maximum DNL of 0.30 LSB and an INL of 0.33 LSB. The midcode glitch is 0.27 pV s. The simulated SNDR and SFDR of the segmented DAC are 52.13 dB and 44.83 dB respectively. The settling of the segmented DAC is 6.02 ns. The power consumption is simulated as 7.88 mW. The prototype will be used in telecommunication applications.
