    Abstract

    This paper presents a low-power LNA for a inductive-coupling tranceiver. Intermittently operating technique to turn on LNA only at the moment when the pulse signal appears is used to reduce power consumption. To optimally control the On-time of LNA, pulse width detector based on self-oversampling TDC is used and compensate the PVT variations of On-time witdh and of pulse signal width. The fabricated test chip in 65nm CMOS occupies 0.06mm2 and achieved the intermittently operating frequency at the range from 60 to 400Mbps. The power consumption is 0.42mW at 400Mbps and the supply voltage of 0.7V which corresponds to 37% power reduction from the power consumption without optimal On-Time Controller.
