本文提出了一种20Gb/s的数字自适应均衡器/判决反馈均衡器（DFE），采用盲采样技术来解决背板通信中因信道长度、损耗和环境变化引起的严重码间干扰（ISI）问题。相比于传统的频谱平衡法和眼图监控法，该设计具有更好的适应性和鲁棒性。
As data rates increase, the backplane communication systems suffer from serious inter-symbol interference (ISI). Due to different channel lengths, loss, and environment variations, an adaptive equalizer is an attractive and robust circuit to equalize the received data in high-speed data communications. Several techniaques are presented for adaptive equalizers. In [1], a spectrum balancing method is presented for an analog equalizer. However, this method is valid only for the random data with fixed data rate. In [5], an eye-opening-monitor (EOM) method adopts a two-dimensional map to detect the signal quality. This EOM method needs a synchronous sampling clock and high-speed comparators. It results in high power consumption and furthermore it requires accurate analog circuits. In this paper, a 20Gb/s digitally adaptive equalizer with blind sampling is presented. Shown in Fig. 25.5.1, this adaptive equalizer consists of an analog equalizer and a decision-feedback equalizer (DFE), a detec
