A WBAN 802.15.6 compliant multi-band re-configurable transceiver for medical applications

The first WBAN 802.15.6 compliant radio system working in MICS/ISM band is reported in this paper. The radio system consists of a transceiver IC and a FPGA-based digital baseband, and is designed for medical applications like wearable and implantable sensors. The transmitter adopts a PLL-based polar architecture, supporting data rate from 10kbps to 4.5Mbps, consuming 2.28mW from 1V VDD supply. The zero-IF based receiver is programmable in terms of noise performance and power consumption for different application scenarios, resulting 2.2mW for noise-figure-optimized mode and 1.9mW for power-efficient mode.
