Abstract

Conventional wearable medical devices need batteries to sustain reliable power for the circuits. Battery replacement is usually inconvenient to the user experience. Wireless power transfer (WPT) could be the solution for this problem. However, wearable medical devices have their intrinsic specifications that could be challenges to the WPT. Their structures should be concise for the wearable needs. Power efficiency should be made as high as possible for prolonging the user experience. Besides, more computing based algorithms embedded in these devices would require more power consumption. How to fulfill these specifications is the aim of this research work. This paper proposes a wireless power processing module that integrate AC-DC and multi- DC-DC power circuits together for wearable medical devices. The AC-DC circuit is specifically designed using a concise topology to enhance power conversion efficiency. The DC power is further regulated by different mode controls to facilitate battery charging or to provide multiple voltage outputs. The integrated circuit is implemented by a 0.25 μm high voltage CMOS process with 1.9 μm × 2.3 μm circuit dimensions.
