The authors propose a hybrid transceiver and an energy-efficient link architecture for bidirectional multipoint-to-multipoint signalling across on-chip global interconnect. The proposed link architecture eliminates the need for passive termination for bandwidth enhancement by means of active termination, reducing the required transmitter signalling current drastically and hence, improving the overall energy efficiency of the link. Also, compared to existing passive terminated interconnect with current-mode receivers at all the points, the proposed link deploys low impedance current-mode receivers providing active terminations at both the ends of the interconnect and high-impedance voltage-mode receivers, which do not consume any portion of the signalling current, at the intermediate nodes of the interconnect which further lowers the required transmitter signalling current. A mixed-mode or hybrid transceiver architecture has been proposed for the aforementioned link, which can act either as a current-mode transmitter or a current-mode receiver or a voltage-mode receiver. The architecture has been implemented in 0.18-μm complementary metal oxide semiconductor technology for an interconnect of length 4 mm and having five transceiver nodes. The total energy efficiency of the architecture is 0.70 pJ/b for a speed of 3.0 Gb/s.

混合双向收发器，用于跨片上全局互连的多点对多点信令

作者提出了一种混合收发器和一种节能链接架构，用于跨片上全局互连的双向多点到多点信令。所提出的链路架构消除了通过主动端接来进行带宽增强的被动端接的需要，从而大大减少了所需的发射机信令电流，从而提高了链路的整体能效。另外，与在所有点上都具有电流模式接收器的现有无源端接互连相比，所建议的链路部署了低阻抗电流模式接收器，在互连的两端和高阻抗电压模式接收器的两端均提供了有源端接。消耗信令电流的任何部分，在互连的中间节点处，这进一步降低了所需的发射机信令电流。已经针对上述链路提出了混合模式或混合收发器体系结构，其可以用作电流模式发送器或电流模式接收器或电压模式接收器。该架构已采用0.18μm互补金属氧化物半导体技术实现，长度为4 mm，具有五个收发器节点。对于3.0 Gb / s的速度，该架构的总能量效率为0.70 pJ / b。18微米互补金属氧化物半导体技术，用于长度为4毫米的互连，并具有五个收发器节点。对于3.0 Gb / s的速度，该架构的总能量效率为0.70 pJ / b。18微米互补金属氧化物半导体技术，用于长度为4毫米的互连，并具有五个收发器节点。对于3.0 Gb / s的速度，该架构的总能量效率为0.70 pJ / b。
