A 0.8V 1.1pJ/bit inductive-coupling receiver with pulse extracting clock recovery circuit and intermittently operating LNA

This paper presents a small size, low-power inductive-coupling receiver for wireless proximity communication. Area efficient active inductor peaking is used to expand the bandwidth of low voltage LNA. Proposed LNA can operate intermittently, synchronized with received pulse timing and reduces the power consumption at low data rate. Clock is extracted from the received pulse signal by simple combination of imbalanced inverters. The fabricated test chip in 65nm-CMOS occupies 0.035mm² and achieved 1.6Gbps with power consumption of 1.76mW at 0.8V power supply.
