本論文利用堆疊式線圈實現高效率振幅鍵控無線能量傳輸架構，首先由磁諧振理論了解影響線圈效率的因素，嘗試提高線圈品質因子來增加效率，並利用ADS進行堆疊線圈設計與模擬。量測結果發射線圈與接收線圈Q值分別為179及76，在發射與接收線圈距離1cm和4cm時分別做阻抗匹配，其效率分別為86%及41%。接著利用上述設計堆疊線圈實現振幅鍵控無線能量傳輸架構，電路總功耗為27mW，整體效率在線圈距離1cm時 DE與PAE分別為55%與49%，傳輸速率最高可達1Mbps。

This thesis implementsa wireless power transfer system in which an ASK data link is performed. A stacked coil structure is used to boost transfer efficiency of the system. The study begins with the theory of magnetically-coupled resonators and highlights the factors that affect the coil efficiency. To optimize transfer efficiency, of the system, the main effortis to enhance quality factor of the coils. The measured quality factors of the stacked coils in the transmitter and receiver are179 and 76, respectively. For the transmitter and receiver coils spaced 1 and 4 cm apart, the coil efficiency achieves 86% and 41%, respectively. The wireless power transfer system consumes about 27 mW DC power. With the transmitter and receiver coils spaced 1-cm apart, the system achieves a DE and PAE of 55% and 49%, respectively, and an ASK data rate of up to 1 Mbps.
