摘要
介绍一种多相位改进型R-2R梯形DAC电路,它适合于ASIC或混合设计的梯形DAC电路,使许多应用电路中所使用的传统的CMOS多相DAC电路中元件更少,微调程序更简单。
An Improved Multiple R-2R Ladder-shape DAC circuit is introduced in this paper. This ladder-shape DAC applys to ASIC and mixed design, and makes fewer elements than that used in traditional CMOS multiphase DAC for many applications. In the same time, it will predigest the trimming procedure.
