本文提出了一种基于毫米波（125 GHz）的超短距离（122 mm）非接触式波连接器（CWC）的消费者互连应用。传统的USB、HDMI、DP和Thunderbolt等互连标准中的高速连接器不仅价格昂贵，而且在机械可靠性和信号完整性方面的性能较差，往往成为高性能计算系统的瓶颈。拟议的CWC利用125 GHz CMOS发射器（TX）、接收器（RX）和紧凑型FR 4 PCB天线来实现高速（> 10 Gb/s）、低成本和高能效的连接器解决方案。开关键控（OOK）调制用于非相干收发器（TRX）架构。此外，天线设计在FR 4 HR基板上，以与现有基础设施兼容。CMOS TX和RX通过倒装芯片工艺与天线组装在一起。所展示的CWC在1.1V电源下总共消耗60 mW的功率，同时传输14 Gb/s的数据速率，实现4.28pJ/bit的能量效率。
This paper presents a millimeter-wave (125GHz) based ultra-short distance (∼2mm) contactless wave-connector (CWC) for consumer interconnect applications. Conventional high-speed connectors in interconnect standard such as USB, HDMI, DP, and Thunderbolt are not only expensive, but also suffer poor performance in both mechanical reliability and signal integrity often becoming a bottleneck in high-performance computing systems. The proposed CWC exploits a 125GHz CMOS transmitter (TX), receiver (RX), and compact FR4 PCB antenna to realize high-speed (>10Gb/s), low-cost, and energy-efficient connector solutions. An on-off keying (OOK) modulation is utilized for a non-coherent transceiver (TRX) architecture. In addition, antennas are designed on an FR4HR substrate for a compatibility with an existing infrastructure. The CMOS TX and RX is assembled with the antenna through a flip-chip process. The demonstrated CWC draws a total of 60mW of power under 1.1V supply while transferring 14Gb/s of data rate, achieving 4.28pJ/bit energy efficiency.
