Abstract

An integrated 3–5 GHz impulse radio ultra-wideband (IR-UWB) transceiver system on chip (SoC) for wireless body area network (WBAN) applications is presented. To enhance system robustness against narrow band interference (NBI) signals, receiver low noise amplifier (LNA) input matching network is optimized to reject out-band NBI. A noncoherent energy detection scheme using analog squarer with band-pass filtering is utilized to increase the rejection to both in-band/out-band NBI. A low-power pulse synchronization algorithm is implemented in the digital baseband. The proposed transceiver achieves energy efficiency of 0.3 and 4.3 nJ/bit for TX and RX respectively and a receiver sensitivity of − 92 dBm (BER = 10−3) for UWB on-off keying (OOK) signal at 1 Mb/s pulse rate. The measured maximum in-band/out-band SIR for BER = 10− 3 is −33 and − 47 dB, respectively.
