Inductive Transceiver for Volume- Constrained Microsystems
نویسندگان
چکیده
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 frontend. The 2.5mm 2 transceiver draws 19.9μA from a 2mm 2 thin-film battery at 40.7kbps.

Nuclear magnetic resonance (NMR) spectroscopy enables non-invasive chemical studies of intact living matter. However, the use of NMR at the volume scale typical of microorganisms is hindered by sensitivity limitations, and experiments on single intact organisms have so far been limited to entities having volumes larger than 5 nL. Here we show NMR spectroscopy experiments conducted on single int...
