Description
Summary:A pulse-based ultra-wideband transceiver (UWB-IR) operating in the 3.25-4.75 GHz band designed for low power and high data rate communication is implemented in 0.18 mum CMOS technology. When 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 [1]. Compared to UWB transceivers reported in the literature, this chip dissipates the lowest energy per bit. In addition, 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 that is able to co-exist with systems operating in the 2.4 GHz and 5 GHz ISM bands as well as interfering systems operating within the signal band. The receiver provides a maximum voltage gain of 82 dB. Within the band of interest and at a typical gain of 57 dB, overall noise figure of 4.5 to 5.4 dB, IIP3 of -5 to -10 dBm, and 47 dB channel-to-channel isolation are measured. The receiver can tolerate in-band and out-of-band narrowband interferers that are as large as -20 dBm and 0 dBm, respectively. The mostly digital programmable transmitter delivers maximum output swing of 800 mVpp to a 50-ohm antenna at rates as high as 1.5 Gbps.
