面向移动医疗芯片的设计研究

Research, Design and Implementation of a System-on-Chip Solution for Mobile Healthcare

便携式医疗仪器与无线通信技术以及网络技术的结合,使移动医疗成为可能。考虑到移动生理参数监测设备的特殊应用条件,面向移动医疗的芯片设计面临低功耗、低频率和低噪声的挑战。本文设计的SoC芯片采用低频率、低噪声、低功耗(三低)的设计方案,主要研究四个方面的内容,即全差分模拟前端、电源管理、人体近端无线通信、数字信号协处理器和系统集成。

The combination of portable medical instruments, wireless communication technologies and Internet makes the growth of mobile medical applications possible. Taking into account the specific demands of physiological parameter detecting in mobile environment, the design of mobile medical applications faces a number of requirements, such as achieving low power consumption, low-frequency operation and low noise emissions. The present paper covers four aspects of our research work, i.e. implementation of fully differential analog front-end, power management, human body communication, and on-chip integration of digital signal co-processor. The System-on-Chip design is based on the 3-L principle: Low-frequency, Low-noise and Low-power.
