针对片上全局互连和硅内插通道，提出了一种节能的3 Gb/S电流模式接口方案。收发信机核心由一个开漏发射机和一个电流读出放大器负载组成，其中开漏发射机具有单抽头预加重功能。电流读出放大器负载通过堆叠PMOS二极管级和交叉耦合的NMOS级形成，提供了没有任何偏置电流的最佳电流模式接收器。用两个65 nm CMOS光收发器实例验证了该方案的有效性。10 mm点对点纯数据通道的能效为9.5 fJ/b/mm，20 mm四分支源同步链路的能效为29.4 fJ/b/mm，包括时钟和数据通道。
An energy-efficient 3 Gb/s current-mode interface scheme is proposed for on-chip global interconnects and silicon interposer channels. The transceiver core consists of an open-drain transmitter with one-tap pre-emphasis and a current sense amplifier load as the receiver. The current sense amplifier load is formed by stacking a PMOS diode stage and a cross-coupled NMOS stage, providing an optimum current-mode receiver without any bias current. The proposed scheme is verified with two cases of transceivers implemented in 65 nm CMOS. A 10 mm point-to-point data-only channel shows an energy efficiency of 9.5 fJ/b/mm, and a 20 mm four-drop source-synchronous link achieves 29.4 fJ/b/mm including clock and data channels.
