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

This paper 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 biassupply 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, energyefficient and interference robust solution for massive short-range interconnects.
