Abstract
To design high-resolution and high-speed current-steering digital-to-analog converter (DAC), both amplitude and timing mismatches should be minimized. In this paper, a dynamic mapping method based on the combination of magic-square-mapping (MSM) and random-segment-selection (RSS) is proposed to improve the performance of DAC. A design example of 12-bit 500-MS/s current-steering DAC is used to illustrate the advantages of the proposed dynamic mapping method. The design is verified by the Monte Carlo simulation, which attains more than 90dB SFDR across the Nyquist bandwidth.
为了设计高分辨率和高速的电流转向数模转换器(DAC)，幅度和时序失配都应该最小化。为了提高DAC的性能，本文提出了一种基于魔方映射(MSM)和随机段选择(RSS)相结合的动态映射方法。通过一个12位500 ms /s电流转向DAC的设计实例，说明了所提出的动态映射方法的优点。通过蒙特卡洛仿真验证了该设计，在奈奎斯特带宽上实现了超过90dB的SFDR。
