隨著科技的進步與人類對於健康管理的需求，工程科技與生物醫學的結合發展將帶給人們便利與許多新的契機，人體植入晶片的應用，即是半導體科技與生物醫學的結合產物，現今的生醫植入系統晶片逐漸發展成為無線電源傳輸架構，不僅能夠減少使用者的不舒適感，也改善植入裝置電池壽命的問題，而透過雙向的資料傳輸，我們可以控制植入系統，也可以從植入系統獲得資訊。
本研究論文中，建立一個無線電源傳輸與資料的收發電路，晶片端包含的Power Regulator、ASK(Amplitude Shift Keying)解碼器與FSK(Frequency Shift Keying)編碼器構成，使用TSMC 0.18μm CMOS製程，總面積為0.031mm^2(不包含PAD)。傳輸系統利用線圈電磁場耦合接收外部電源與資料，Power regulator產生穩定電源提供給晶片內部或其它電路，ASK解碼器負責解調接收到的ASK訊號，解調植入裝置的控制訊號，並且提供植入裝置時脈訊號，而FSK編碼器可將植入裝置欲傳輸的資料訊號進行編碼，在透過線圈耦合傳出。
本論文提出一個無電阻電容、具有高效率資料傳輸、可靠度高、並且可彈性應用的ASK 解碼電路，其Modulation Index可低達4.05%、Modulation Rate為50%，利用自我解調(Self-Sampling)的概念架構，能同時把時脈訊號與資料一起解碼出來，提供植入晶片系統的時脈與資料，實用性高、擁有穩健的解調功能，不受限於製程上的誤差而喪失功能，在面積與功率也不會消耗太大的系統資源。並且可以彈性控制其Modulation Index隨著不同的應用系統而改變。

Biomedical implantable devices have appeared for more than fifty years. With more understandings of neuroscience, some diseases caused by neural abnormal discharge or disable may be cured or improved by neural stimulation techniques. Most of the wireless implantable devices transmit power and data into the no-battery implantable device by magnetic coupling. And the bidirectional data transmission, we can control and monitor the implantable system.
This thesis presents the wireless power and bidirectional data transmission for biomedical implantable SoC. The chip contains power regulator, ASK (Amplitude Shift Keying) demodulator and FSK (Frequency Shift Keying) modulator, using the TSMC 0.18μm CMOS processing. The chip size is 0.031mm^2.(Without PAD) The transmission system utilizes coils electric magnetic field coupling the power and data into the chip, Power regulator produces the stability power for chip and other circuits. The ASK demodulator can decode the ASK signal and provide the clock signal. The FSK modulator can encode the implantable device data signal which wanted to transmit out, and transmitted through coil coupling.
This study presents a novel ASK demodulator using the self-sampling structure for biomedical implantable devices. The modulation index and modulation rate are relative to power transmission efficiency. Results show that with a 2MHz carrier, the proposed ASK demodulator structure has a minimum modulation index down to 4.05% and a 50 % maximum modulation rate. The ASK demodulator also has a controllable modulation index and maintains a constant high-efficiency modulation rate for biomedical implantable systems.
