摘要: An efficient synchronous active rectifier and Multi Feedback low drop out (LDO) Regulator coupled with a wireless power receiver (WPR) is proposed in this study. maximum conversion efficiency (PCE) of 94.2% to mitigate the reverse leakage current using zero sensing. Output voltage are regulated by multi-feedback LDO regulator, sharing single path transistor. The chip fabricated 0.18 μm BCD technology having die area 16.0 mm2. A load 800 mA measured for rectifier.
