隨著科技不斷的進步，造就了生醫植入式裝置誕生，對人類醫學帶來了重大改變。而由於半導體製程的發展，減少了整體裝置的大小以及耗電，讓植入式裝置在設計上有更有彈性。現今的植入式裝置結合了無線能量及資料傳輸，不但改善了電源供應的問題，在使用上也更加方便。
本論文提出一個交流對直流轉換器，結合了整流器以及直流對直流轉換器的控制電路，可以同時達到整流以及穩壓的功能，減少整體電路所使用的面積及能量的消耗。此電路同時會將輸出負載訊息以LSK(Load Shift Keying)回傳至外部裝置，我們可以透過回傳的訊號判斷輸入的能量是否過量或不足，提升整體系統的效率。電路使用TSMC 90nm 1P9M製程，總面積為0.071mm2(不包含Pad)。此電路可以在輸入交流電壓1.5V至2V，頻率1至10MHz的情況下產生1V的直流電壓以及10mA最大輸出電流。
在本研究論文中，建立了一個無線能量與資料傳輸的電路，晶片端包含了所設計的交流對直流轉換器電路，整個傳輸系統利用線圈將外部能量以電磁耦合的方式傳輸，接收到的能量透過交流對直流轉換器產生穩定的電源供植入端電路使用。同時將輸出負載訊息以LSK的方式回傳至外部裝置，回傳的訊號將過解調之後，可以用來控制輸出能量的大小，讓植入端電路可以接收到適當大小的能量。

The implant device is created with the developing of the technology, and it causes the large change to medical science. With the evolution of the semi-conductor process, the size and power consumption of total device are reduced, making the implant device is more complex in design. Now implant device is combined with wireless power and data transmission, and it not only improves the problem of power supplying but also becomes more convenient in using.
This thesis presents an AC-DC converter. This circuit is combined with the rectifier and the controller of the DC-DC converter, so it can get the function of rectification and regulation at the same time, and reduce the area and power consumption of the total device. This circuit also transfers the loading condition back to the external device by LSK (Load shift keying). We can use the feedback signal to determine if the input power is not enough or excessive, which increases the efficiency of the total system. The circuit is fabricated with the TSMC 90nm 1P9M process. The circuit area is 0.071mm2. The circuit can produce a 1V DC voltage with maximum output current of 10mA from an AC input ranging from 1.5V to 2V, at 1MHz to 10MHz.
A wireless power and data transmission for biomedical implant SoC is presented in the thesis. The chip contains the presented AC-DC converter. The transmission system utilizes coils inductive coupling the external power into chip, and the AC-DC converter outputs stable voltage for implant circuit. It also transfers the loading condition back to the external device by LSK. After demodulating, the feedback signal can be used to control the output power of external device, which makes the implant device receives the suitable power.
