Abstract: An integrated 3-5 GHz impulse radio ultrawideband (IR-UWB) wireless transceiver SoC for wireless body area network (WBAN) applications is reported in this paper. To enhance system robustness against narrow band interference (NBI) signals, receiver low noise amplifier (LNA) input matching network is optimized to reject outband NBI below 2.5 GHz. A non-coherent energy detection scheme using analog squarer with band-pass filtering is utilized to increase the rejection to both in-band/out-band NBI. The proposed transceiver achieves energy efficiency of 0.3 nJ/bit and 4.3 nJ/bit for TX and RX respectively and a receiver sensitivity of -88 dBm (BER=10-3) for UWB OOK signal at 1 Mbps pulse rate. The measured in-band/out-band SIR is better than -34 dB and -45 dB, respectively.
