A transceiver for communicating over an electronic textiles medium is implemented for body area networks. A supply-rail-coupled differential signaling scheme permits time-sharing of the eTextiles medium between communication and remote powering circuits. Fabricated in 0.18 μm CMOS and operating at 0.9 V, the chip consumes 110 μW at a data rate of 10 Mb/s over a 1 m fabric link.
