摘要

本文介绍了一种用于大规模短距离互连的节能60ghz OOK接收器，解决了配电网络干扰和灵敏度与能效之间的权衡这两个关键问题。采用自定义偏置供电策略的变增益低噪声放大器提高了灵敏度和能效。提出了低q去耦技术，提高了电源干扰容错性，使眼图的开眼量是传统无低q去耦时的2.6倍。通过共同设计低噪声放大器、包络检测器和基带放大器，在65nm LP CMOS工艺中制作了具有上述技术的原型。测量结果表明，最大数据速率可达16 Gbps，能量效率为0.62 pJ/bit，灵敏度为-21.8 dBm，为大规模短距离互连提供了高动态范围、节能和抗干扰的解决方案。

A 0.62-pJ/Bit 60-GHz OOK Receiver With Supply Interference Tolerance for Short-Range Interconnects

This brief presents an energy-efficient 60-GHz OOK receiver for massive short-range interconnects, addressing two key issues including interference in power distribution network and trade-off between sensitivity and energy efficiency. Variable gain low-noise amplifier with custom-designed bias-supply strategy is proposed to improve sensitivity and energy efficiency. Low-Q decoupling technique is proposed to improve supply interference tolerance, resulting in 2.6 times eye-opening in the eye diagram compared to the traditional one without low-Q decoupling. By co-designing the low-noise amplifier, envelope detector, and baseband amplifier, a prototype with proposed techniques was fabricated in a 65-nm LP CMOS process. Measurement results show that it achieves a maximum data rate of 16 Gbps with an energy efficiency of 0.62 pJ/bit and a sensitivity of -21.8 dBm, providing a high dynamic range, energy-efficient and interference robust solution for massive short-range interconnects.
