摘要

电流导向数模转换器(dac)的性能限制是由于有限的输出阻抗、非理想开关、寄生电容、匹配等。在这项工作中，我们提出了一个包含动态非理想性的14位电流导向DAC的动态状态空间模型。给出了仿真结果，并与实测结果进行了比较。该模型可用于D/A转换器的快速性能估计。

Characterization of a CMOS current-steering DAC using state-space models

Performance limitations on current-steering digital-to-analog converters (DACs) are due to finite output impedances, nonideal switches, parasitic capacitances, matching, etc. In this work we present a dynamic state-space model of a 14-bit current-steering DAC which includes dynamic nonidealities. Simulation results are presented and compared to measurement results. The model can be used for fast performance estimation of D/A converters.
