Abstract

This paper presents an inductive coupling wireless power receiver with high efficiency active rectifier and multi feedback LDO regulator. The synchronous active rectifier with the zero current sensing is proposed to achieve the high efficiency minimizing the reverse leakage current. Multi Feedback LDO regulator is proposed to implement the output voltage regulation, over voltage protection, over current limit, and adaptive communication limit sharing the single power transistor. This chip is implemented using 0.18 μm BCD technology with an active area of 4.0 mm × 4.0 mm. The maximum power conversion efficiency of the Active Rectifier is 94.2 % when the load current is 800 mA.
