摘要

在处理移动部件或实施广泛的互连网络时,传统互连器件在机械耐久性、移动性和信号完整性方面面临着巨大挑战。因此,它们往往会阻碍先进的自主和高性能计算系统的性能。本文提出了一种完全可旋转、对角线灵活的超短距离(≈ 1 毫米)无线互连器件。所提出的无线互联由一个 57 GHz 收发器和一个折叠偶极子天线组成,通过线键合实现了灵活的非接触式连接。在这里,两个折叠偶极子在菲涅尔区(辐射近场)进行通信,我们利用纵向电场来缓解整个旋转角度的极化失配。我们采用了非相干开关键控(OOK)调制方案,并使用了自动增益控制(AGC)环路和偏移抵消反馈环路来补偿传输劣化和信号失衡。所提出的系统在 1 V 电源下的功耗为 58.2 mW,数据传输速率为 10Gb/s,实现了 5.82-pJ/bit 的能效。

Energy-Efficient and Rotationally Adjustable Millimeter-Wave Wireless Interconnects
Conventional interconnects experience significant mechanical durability, mobility, and signal integrity challenges when dealing with moving parts or implementing extensive interconnect networks. As a result, they often hinder the performance of advanced autonomous and high-performance computing systems. This paper presents a fully rotatable and diagonally flexible ultra-short distance (≈ 1 mm) wireless interconnect. The proposed wireless interconnect comprises a 57-GHz transceiver integrated with a folded dipole antenna through wire bonding, enabling a flexible contactless connection. Here, two folded dipoles communicate in the Fresnel zone (radiative near-field), where we leverage the longitudinal electric fields to alleviate the polarization mismatch over the entire rotation angle. We have implemented a non-coherent on-off keying (OOK) modulation scheme and employed an automatic gain control (AGC) loop and offset canceling feedback loop to compensate for the transmission degradation and signal imbalance. The proposed system consumes 58.2 mW of power under a 1 V supply while transferring data at a rate of 10-Gb/s, achieving 5.82-pJ/bit energy efficiency.
