本論文中使用了台積電0.18微米CMOS製程設計了一組體內發信器和體外接收器，以應用於作為神經訊號擷取與刺激研究平台的無線植入式深層腦部刺激（DBS）微系統。植入端置於老鼠體內，並使用1 V的供電電壓，體外端擬放置在老鼠的飼養箱之外，與發信器的最長距離約為20公分。

由於在植入端有嚴格的功耗和離散元件使用限制，本論文使用開關式調變（OOK modulation），選用ISM 2.4-GHz頻段（Industrial, scientific, and medical band）做為載波，並以10 Mb/s的速度收發植入式系統所擷取到的神經訊號。植入端使用Direct-modulation scheme的發信器以達到省電的目的。體外端使用了一個Super-regenerative receiver（SRR）進行接收，並且在新版的設計中加入了一個鎖相迴路（Phase-locked loop, PLL）的架構以達到Synchronized解調，以增進其效能。

發信器和接收器均有新舊兩版的設計，而新版的目的為解決在舊版中出現的問題並改良運作表現。在新版設計的TT-corner post-simulation中，發信器在消耗為1.132 mW的情況下達到–5.76 dBm的輸出功率，而接收器在功耗為2.105 mW時達到Sensitivity為–98 dBm，兩者的FOM分別為0.50 nJ/bit/mW和224.8，在相關文獻中為具有競爭力的結果。

本論文在第一章簡介研究背景；在第二章對系統面的考量和設計進行說明，並且回顧過去相關文獻；第三章和第四章分別介紹發信器和接收器的電路設計、呈現模擬與量測結果、進行討論，並且說明新版電路的設計；第五章則以結論和未來工作為全文作結。

In this thesis, a wireless data telemetry uplink for implantable biomedical microsystem studying the mechanisms of deep brain stimulation (DBS) in rat models is proposed. The transceiver operating in the 2.4-GHz Industrial, Scientific and Medical (ISM) band at the data rate up to 10 Mb/s is able to cover the non-line-of-sight (non-LOS) transmission distance for more than 20 cm. While the implanted on-off keying (OOK) transmitter is designed compact to achieve low-power operation, the external super-regenerative receiver features synchronous demodulation by incorporating a phase-locked loop architecture to improve the throughput and frequency selectivity. Designed with the standard 0.18-$\mu$m CMOS technology and with 1-V supply, the direct-modulation transmitter with the output power of –5.76 dBm and the super-regenerative receiver with the sensitivity of –98 dBm consume average power of 1.132 and 2.105 mW, respectively.
