摘要

在生物医学设备发展之前，可充电电池应用的集成能量收集系统的需求是潜在的问题。本文提出了一种锂离子电池充电器无线充电系统，包括交直流倍增器(AC-DC)、线性稳压器(LDO)和充电控制回路，采用多充电相法将对电池的影响降到最低。采用台积电130nm工艺设计了用于植入生物医学设备的锂离子电池充电器，其输入电压为6Vp-p，频率为4MHz，直流输出电压为4.1V，最大直流输出电流为1.5mA。

Li-ion battery charger circuit for biomedical devices

In advance of biomedical devices, the demands of integrated power harvesting system for rechargeable battery applications are underlying issues. This paper presents a wireless power system for Li-Ion battery charger including voltage doubler (AC-DC), voltage linear regulator (LDO) and charging control loop applying multi charging phases method to minimize battery effect. Proposed Li-ion battery charger with input voltage is 6Vp-p at frequency 4MHz, DC output voltage is 4.1V and maximum DC output current is 1.5mA is designed using TSMC 130nm technology for implanted biomedical devices.
