Abstract:
Biomedical Engineering of Electronic Engineering Deparment, Fudan University Shanghai, 200433 Based on the pulse-coded transmitting and wide-band receiving system, this paper describes a research of phase design a special power management circuit according to the particular demands of a real-time and continuously monitor system is essential. Combined with the requirement of voltage and current in separated module, three aspect must be considered, that is, how to select the functional component, how to accomplish voltage converting and how to carry on battery management. The test at last shows that, using this circuit and the 4400 mAh battery the energy utilization is more than 88%, and the work time is more than 20 hours.
