A 95fJ/b Current-Mode Transceiver for 10mm On-Chip Interconnect

📋 论文概要

提出一种用于10mm片内互连的电流模式收发器，通过有源电感均衡技术降低功耗，实现了95fJ/b的能效，并采用自动关断机制减少静态功耗。

💡 主要创新点

• 采用有源电感配置的PMOS二极管作为接收器负载，无需额外功耗即可实现均衡。
• 电流感测电路仅作为开漏发射极的负载，接收器无额外直流路径，发射机关断时自动关闭。
• 在10mm互连长度下实现了95fJ/b的极低能耗。

sense-amplifier load in the receiver. In this work, IDRV and IPE were set to 95μA and 45μA, respectively. For the receiver equalization, the PMOS diode in the sense-amplifier load is modified to form an active inductor configuration without any extra power consumption. Since the current-sensing circuit is attached only as the load of the open-draintype transmitter, there is no additional DC current path in the receiver. So the current sense-amplifier load is automatically turned off when transmitter is off. 2 Data communication between local system blocks through on-chip global interconnects presents significant design challenges in scaled VLSI systems. The goal of this research is to reduce the energy consumed per bit transmitted, while
