| Abstract | A pulse-based ultra-wideband transceiver (UWB-IR) operating in the 3.25 - 4.75 GHz band designed for low power high data rate communication is implemented in 0.18 µm CMOS technology. Operating at 1 Gbps data rate, it dissipates 98 mW (98 pJ/b) in the receive-mode and 108 mW (108 pJ/b) in the transmit-mode from a 1.8-V supply while achieving a combined TX/RX EVM of -32 dB. The combination of the frequency channelized architecture, high-linearity RF circuits, aggressive baseband filtering and low local oscillator spurs results in an interference-tolerant receiver, having the ability to co-exits with systems operating in the 2.4 GHz and 5 GHz ISM bands as well as systems in its unlicensed band of operation of the receiver. The receiver provides maximum gain of 82 dB, overall noise figure in the range of 4.5 - 5.4 dB, IIP3 of -5 to -10 dBm, and 47 dB channel to channel isolation. The receiver suffers a performance degradation of less than 3 dB in EVM in the presence of in-band and out-of-band interferers as large as -20 dBm and 0 dBm, respectively. The mostly digital transmitter delivers output swing of 800 mVpp to a 50-ohm antenna at rates as high as 1.5 Gbps. |
