A fully integrated 0.18um CMOS UWB SoC for wireless body area network applications

A fully integrated 3 – 5GHz CMOS transceiver SoC for WBAN is presented in this paper. To achieve the low power and low complexity, OOK receiver architecture and the digital impulse generator are employed. For the rejection of the undesired interferers, the tunable RF notch filter is integrated and measured results show more than 9 dB improvement of the sensitivity. The measured energy efficiency of transmitter and the receiver sensitivity are 20.6 pJ/bit and −86.5 dBm, respectively.
