摘要

设计了一种用于高速背板接收机的6.25 Gb/s双抽头决策反馈均衡器(DFE),采用0.18 μ m CMOS芯片。半速率DFE的流水线结构使传输数据速率比传统DFE提高,而面积增加很小。近端数据为6.25 Gb/s的PRBS10, 0.5 Vp-p, DFE恢复数据测量抖动(pp)为3 ps,水平睁眼0.97 UI,垂直睁眼0.48 V。

A 6.25 Gb/s Decision Feedback Equalizer used in SerDes for High-speed Backplane Communications
A 6.25 Gb/s two-tap DFE (decision feedback equalizer) in high-speed backplane receiver has been designed in a 0.18-mum CMOS. The pipelined architecture in the half-rate DFE achieves an increase in the transmitted data rate over conventional DFE with a small increase in area. Near end data is a 6.25 Gb/s PRBS10 with 0.5 Vp-p, and the DFE recovered data has been measured with jitter (pp) of 3 ps and a horizontal eye-opening of 0.97 UI, a vertical eye opening of 0.48 V.
