本文提出了一种12Gb/s、可恢复39dB信道损耗的无时钟DFE接收器，采用双向均衡技术来解决高速背板通信中的码间干扰问题。该设计通过无时钟架构和双向均衡，简化了时序恢复并提高了均衡效果。
Reggio Emilia, Modena, Italy 3 University of Pavia, Pavia, Italy 2 Backplane communications are rapidly moving beyond 10 Gb/s both in networking and in hard-disk drive interconnection. Decision Feedback Equalization (DFE) and Duobinary (DB) prove to be effective techniques assuring signal integrity in the presence of ISI, but with speed increase the accuracy of the timing recovery brings additional challenges. Half-rate clock DFEs by loop-unrolling are widely applied to avoid feeding back the decided bit within a 1-bit (UI) time, but the alternated eye opening that is created requires an increased circuit complexity to obtain the maximum accuracy in timing recovery [1][2][3]. DB alternative may suffer in the presence of long sequences of incoming toggle patterns (1010...).
