Abstract: In this paper a single chip CMOS front-end transceiver for ultra-wideband (UWB) radio is presented. This is the first paper to present the whole transceiver circuits for pulse based UWB. The transceiver consists of mostly digital circuits except LNA and mixer which are simulated for 0.18m CMOS technology. The power consumption of LNA can be reduced by switching the bias current which is the advantage of the discontinuous feature of the pulse based UWB. The receiver design is tested against PVT variations by running Monte-Carlo simulations. As the results, the power consumption of the transceiver is 0.44mW at 10Mpps (pulse per sec) and 2.5mW at 50Mpps.
