Conclusions
An interference robust IR-UWB transceiver SoC for WBAN application is presented
in this chapter. Energy efficiency of 0.3 and 4.5 nJ/bit are achieved for TX and RX
respectively and the measured receiver sensitivity is
91.5 dBm at 1 Mb/s data
rate. A low-power pulse synchronization algorithm for clock and data recovery is
implemented in digital domain without any need for PLL/DLL or ADC. The proposed
transceiver SoC has been successfully incorporated into a continuous vital signal
monitoring system and the performance is validated by experiments.
