摘要

提出了一种适用于低功耗无线生物医学传感器的全集成(开关键控)脉冲无线电超宽带(IR-UWB)发射机。发射机工作在3-5 GHz频率范围内，信道带宽为~2GHz。该发射机采用标准130纳米CMOS工艺实现，采用开/关键控(OOK)调制方案，在1.2 V电源电压下平均功耗为496 μW。仿真结果表明，脉冲持续时间为3.5ns，功率谱峰值幅值为-46.8 dBm/MHz，完全符合FCC频谱掩模要求。

Impulse radio ultra-wideband (IR-UWB) transmitter for low power low data rate biomedical sensor applications

This paper presents a fully integrated (on-off keying) impulse radio ultra-wideband (IR-UWB) transmitter suitable for low-power wireless biomedical sensors. The transmitter operates at 3-5 GHz frequency range with a channel bandwidth of ~2GHz. Implemented in a standard 130-nm CMOS process the proposed transmitter follows on/-off keying (OOK) modulation scheme and consumes an average power of 496 μW with 1.2 V supply voltage. Simulation results show that the pulse duration is 3.5ns and the peak amplitude of the power spectrum is -46.8 dBm/MHz and which fully complies with the FCC spectral mask.
