Abstract

The design and implementation of a fully integrated transceiver front-end for biomedical data is reported. The system targets the transmission of force data from a distributed sensor system for on-body application. A prototype force transducer patch is presented whose parasitic capacitance is exploited as coupling capacitance for body-channel transmission. The transceiver is implemented in 0.35 μm CMOS technology and occupies an area of 0.0178 mm2. It consumes 360 μA of current at a supply voltage of 3 V. Measured results further confirm a transmission rate of 54 kb/s making the design suitable for use in a distributed pressure sensing network.
