摘要

提出了一种采用远端串扰(text)补偿技术的20 Gb/s/引脚单端发射机。电容峰值驱动器(CPD)补偿ext。利用每个发送器中序列化器前的数据，预测了ext的效果。从而消除了补偿数据和传输数据的时延差异。补偿文本的数据延迟调整，从而有可能在相邻通道之间的不同飞行时间有最佳的开眼。该架构采用65nm CMOS工艺设计。所设计的变送器在电源电压为1v时，宽度为39.3 ps，高度为43.2 mV。

A 20Gb/s/pin Single-ended Transmitter with FEXT Compensation Technique

A 20 Gb/s/pin single-ended transmitter with far end crosstalk (FEXT) compensation technique is proposed. The capacitive peaking driver (CPD) compensates the FEXT. Using the data before serializer in each transmitter, effect of FEXT is predicted. So, the difference of latency between data for compensation and transmission is eliminated. The delay of data for compensating FEXT adjusted, thereby it is possible to have optimal eye-opening for different flying-times between adjacent channels. The proposed architecture is designed with 65nm CMOS process. The designed transmitter has eye-opening of width with 39.3 ps and height with 43.2 mV at supply voltage of 1-V.
