摘要

本文描述了一个接收器数据路径的低功耗实现，包括带有ESD的RX终端、连续时间线性均衡器(CTLE)和一个以四分之一速率运行的15分路决策反馈均衡器(DFE)。虽然前3个DFE抽头是通过推测实现的，但后12个抽头使用开关盖(SC-DFE)方法。该电路采用32nm SOI-CMOS制作，在36dB损耗通道上以< 10-12 BER接收30Gb/s PRBS31数据，能量效率为3.1mW/Gbps。

A 3.1mW/Gbps 30Gbps quarter-rate triple-speculation 15-tap SC-DFE RX data path in 32nm CMOS

This paper describes a low-power implementation of a receiver data path, consisting of the RX termination with ESD, continuous-time linear equalizer (CTLE), and a 15-tap decision feedback equalizer (DFE) running at quarter rate. While the first 3 DFE taps are implemented by speculation, the latter 12 taps use a switched-cap (SC-DFE) approach. The circuit was produced in 32nm SOI-CMOS, and was measured to receive 30Gb/s PRBS31 data at <;10-12 BER over a 36dB loss channel with an energy efficiency of 3.1mW/Gbps.
