摘要

人体通信作为人体传感器网络的一种新兴的通信方式

有着突出的优势与巨大的潜力。介绍了应用在人体通信无线收发器的压控振荡器（VCO）的设计与测试。该模块采用了四级双差分结构

采用SMIC 0.18μm 1P6M工艺

核心面积仅为0.02 mm2。测试结果显示:在1.8 V供电电压下

VCO调谐范围为30～130 MHz

在80 MHz输出频率下

1 MHz频偏处相位噪声为-98 dBc/Hz

最大功耗仅为1.27 mW

较好地满足了采用人体通信作为通信方式的人体传感器网络的要求。

Abstract

Human body communication

as a new communication mode of body sensor network

has shown outstanding advantages and potential.A voltage controlled oscillator（VCO）for human body communication is presented.The module adopts a 4 stage fully differential structure and the technique of SMIC 0.18 μm 1P6M is adopted.The core area is about 0.02 mm2.The measurement results show that the VCO has an operating frequency range 30

30 MHz at 1.8V supply voltage.At 80 MHz

the phase noise at 1 MHz frequency offset is-98 dBc/Hz.And the maximum power consumption is only 1.27 mW.It satisfies the requirement of body sensor networks based on human body communication very well.
