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 whole transceiver circuits for pulse based UWB. The transceiver consists of mostly digital circuits except the LNA and mixer which are simulated for 0.18 μm 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 per the results, the power consumption of the transceiver is 0.44 mW at 10 Mpps (pulse per sec) and 2.5 mW at 50 Mpps.
