This research paper presents a 12-bit 8–4-segmented current-steering DAC (digital-to-analog converter) that offers notable advantages, particularly in terms of its reduced power consumption compared to other similar designs. The exceptional performance of our DAC can be attributed to two key factors: the use of a thermometer encoder and an efficient digital input bit segmentation. These features contribute to enhanced precision and reduced power requirements, setting our DAC apart from the existing solutions in the field. These enhancements significantly reduce glitches and improve the accuracy of the DAC’s output. DAC dissipates a total power of about 44.95$$mW when running at a sample rate of 1.2$$GHz with the CMOS technology of 45$$nm. While the supply input voltage is held constant at 1.2$$V, the DAC’s digital input is pulsating in nature in which the ON voltage is 1$$V and OFF voltage is 0$$V. Also, the DAC has a spurious-free dynamic range (SFDR) of 41.77$$dB.

本研究论文介绍了一种 12 位 8-4 段电流导引 DAC（数模转换器），它具有显着的优势，特别是与其他类似设计相比，其功耗更低。我们的 DAC 的卓越性能可归因于两个关键因素：温度计编码器的使用和高效的数字输入位分段。这些功能有助于提高精度并降低功耗要求，使我们的 DAC 有别于该领域现有的解决方案。这些增强功能显着减少了毛刺并提高了 DAC 输出的准确性。 DAC 消耗的总功率约为 44.95$$以 1.2 采样率运行时的 mW$$GHz 采用 45 CMOS 技术$$纳米。当电源输入电压保持恒定在 1.2$$V，DAC 的数字输入本质上是脉动的，其中导通电压为 1$$V 和 OFF 电压为 0$$V. 此外，DAC 的无杂散动态范围 (SFDR) 为 41.77$$D b。
