摘　　要：动态血糖监测有助于糖尿病人监控血糖、控制病情。在动态血糖监测仪器设计中,微处理器是影响系统功耗的重要因素。为了最大限度地延长连续监测时间,论文提出了一种基于高速、高集成度的混合信号片上系统级单片机C8051F040的动态血糖监测系统的低功耗设计方案,采取了一系列的硬件和软件优化措施,通过理论计算和实测,给出了在连续血糖监测条件下系统功耗的优化方法。结果显示,使用一节5号电池供电,系统可以连续工作400小时以上。Continuous Glucose Monitoring is helpful for diabetic patients to control disease progression. In continuous glucose monitoring system, microprocessor is one of important factors for power dissipation. A low power design based on C8051F040, a kind of mixed-signal SOC with high integration, high-speed is provided in this paper. Some hardware and software measures are used to lower the power consumption. Through theoretical calculation and measurement, a method to optimize the power dissipation in continuous glucose monitoring task is provided.The result shows that the system continuous working time is more than 400 hours with single 5# battery supply
