本研究中使用台積電CMOS 0.18 μm 1P6M製程，設計並實作了一個應用於生醫頻帶(MICS Band)之植入式無線發射機。使用了能量獲取(Energy Harvesting)的技術來當作整體發射機的電源供給，同時也使用這個信號並透過注入鎖定式除頻器(Injection-Lock Frequency Divider)產生發射機的載波訊號，接著將資料透過振幅偏移調變(Amplitude-Shift Keying, ASK)電路結合載波訊號再藉由功率放大器(Power Amplifier)送出。
發射機的操作頻率為402 MHz，電流消耗為0.91 mA，輸出功率為-9.6 dBm，其載波訊號在透過射頻訊號輸入頻率為1608 MHz大小為8.5 dBm的信號供電並且鎖定電路時，發射機輸出頻率為402 MHz載波之相位雜訊(Phase Noise)在1 MHz偏移時為-123.43 dBc/Hz。在輸入訊號大小為9 dBm時，透過調變機制後所能送出的資料速率大約為30 kb/s。

In this thesis, a low power transmitter for biomedical implant is proposed and implemented using TSMC CMOS 0.18 μm 1P6M process. This transmitter applied two different techniques by the same input signal. Energy harvesting technique for powering up whole transmitter circuits, and injection-lock technique for synthesizing carrier of the transmitter. The modulation type of the transmitter is amplitude shift keying modulation. The data and the carrier will be modulated by ASK modulator, after modulation the signal could be delivered out through power amplifier.
This transmitter operating under wireless power mode when the input signal strength is larger than 8.5 dBm. The carrier frequency is locked at 402 MHz by the 1608 MHz input frequency with phase noise -123.43 dBc/Hz at 1 MHz offset. The current consumption is 0.91 mA with -9.6 dBm output power. The data rate is about 30 kb/s under 9 dBm input signal strength.
