Abstract :
A 1.6nJ/bit inductive transceiver targeting volume-constrained microsystems with limited peak current is presented. The transceiver uses a protocol in which the external unit sends the same packet multiple times to shift the power consumption burden to the external TRX unit and relax jitter requirements on the mm-scale receiver. The transceiver receives data from a 2W external unit at 1m distance using a dual-coil LNA design and fast-startup front-end. The 2.5mm2 transceiver draws 19.9μA from a 2mm2 thin-film battery at 40.7kbps.
