Based on study and analysis of lots of mainstream 12-bit current-steering DACs, including their typical structures, current calibration and decode methods as well as the layout placement, the SPEC, (specifications) of the DAC were proposed.

• 论文在广泛调研分析当前主流12位current-steering DAC的典型结构以及电流校正方式、解码方式与版图布置方式基础上,参考同类产品的参数,确定了DAC的设计规范。
