对超高速互连的不断扩大的需求已经推动了以每通道> 100 Gb/s操作的有线TX的发展[1]-[4]。本文提出了一种PAM-4 TX，实现200 Gb/s的改善输出带宽和输出摆幅最小化的驱动器电容与上拉电流源，多路复用与灵活的时钟时序控制，并采用完全可重构的5抽头FFE架构。
The ever-expanding demand for ultra-high-speed interconnects has driven the development of wireline TXs operating at >100Gb/s per lane [1]–[4]. This paper presents a PAM-4 TX achieving 200Gb/s with improved output bandwidth and output swing by minimizing the driver capacitance with pull-up current sources, multiplexing with flexible clock timing control, and employing a fully reconfigurable 5-tap FFE architecture.
