本文介绍了一种奈奎斯特速率电流舵数模转换器，在265 MHz信号频段内，该转换器的峰值无杂散动态范围优于87 dB，峰值信噪比优于77 dB。该器件采用完全集成的数字校准技术，可测量并消除第一奈奎斯特频带内的静态和动态失配误差，还采用各种电路级技术，可减轻抖动和码间干扰的影响。
This paper presents a Nyquist-rate current-steering digital-to-analog converter that achieves a peak spurious-free dynamic range better than 87 dB and a peak signal-to-noise-and-distortion ratio better than 77 dB over a 265-MHz signal band. It is enabled by a fully integrated digital calibration technique that measures and cancels both static and dynamic mismatch errors over the first Nyquist band, and various circuit-level techniques that mitigate the effects of jitter and inter-symbol interference.
