摘要

We present a scalable low-power I/O transceiver in 65 nm CMOS, capable of 5–15 Gbps operation over single-board and backplane FR4 channels with power efficiencies between 2.8–6.5 mW/Gbps. Nonlinear power–performance tradeoff is achieved by the use of scalable transceiver circuit blocks and joint optimization of the supply voltage, bias currents and driver power with data rate. Low-power operation is enabled by passive equalization through inductive link termination, active continuous-time RX equalization, global TX/RX clock distribution with on-die transmission lines, and low-noise offset-calibrated receivers.
