An IR-UWB RF transceiver for high-rate WBAN applications

Abstract

An IR-UWB RF transceiver IC compliant with IEEE 802.15.6 WBAN is implemented in 0.18 µm CMOS technology. To achieve the low power and low complexity, the OOK receiver architecture using energy detection and the digitally synthesized transmitter are employed. For the rejection of the undesired interferers and DC offset, the RF active notch filter and the proposed DC offset reset switch are integrated and improve the sensitivity significantly. The measured sensitivity of the receiver is −87.5 dBm at 4 GHz with 1.579 Mbps. The power consumption of the receiver and transmitter are 57 mW and 0.4 nJ/bit respectively.
