A 108/98 pJ/b 1Gbps Fully Integrated Interference Tolerant Frequency Channelized UWB Transmitter/Receiver

A pulse-based UWB transceiver operating in the 3.25-4.75GHz band is implemented in 0.18μm CMOS technology. At 1Gbps data rate, it dissipates 98mW (98pJ/b) in the receive-mode and 108mW (108pJ/b) in the transmit-mode while achieving a combined Tx/Rx EVM of -32dB. The receiver provides maximum gain of 82dB, 4.5-5.4dB NF, -5 to -10dBm IIP3, and 47dB channel to channel isolation. The transmitter delivers output swing of 800mVpp to 50-ohm load at rates as high as 1.5Gsps.
