摘要

采用0.18 μ m CMOS技术实现了3.25-4.75 GHz频段的脉冲超宽带收发器。在1 Gbps的数据速率下，它在接收模式下消耗98mW (98pJ/b)，在发送模式下消耗108mW (108pJ/b)，同时实现-32dB的Tx/Rx综合EVM。该接收机提供82dB的最大增益，4.5-5.4dB NF， -5至-10dBm IIP3, 47dB通道到通道隔离。发射器以高达1.5Gsps的速率为50欧姆负载提供800mVpp的输出摆幅。

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

A pulse-based UWB transceiver operating in the 3.25-4.75 GHz band is implemented in 0.18 mum CMOS technology. At 1 Gbps 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.
