| dc.description.abstract | 近年來，全球對於醫療和電子整合的意識抬頭下，使得電機領域以及醫療領域的人才交流逐漸熱絡，從英特爾M2M工作坊、研討會舉辦的頻率以及醫療電子臨床導入課程的開辦就可看出端倪。因此在這樣的趨勢背景下，本論文將針對生醫電子系統提出兩種不同的應用 ─ “整合型低電壓發射機”及 “可攜式核磁共振收發機”。
本篇論文所提出的整合型低電壓發射機實作在TSMC CMOS Standard 0.18um製程下，主要應用於MICS頻帶。而此發射機包含以下的電路區塊 ─ 電壓控制振盪器(voltage control oscillator)、前置放大器(pre-amplifier)、功率放大器(power amplifier)以及後級的被動匹配網路(Matching Network)。訊號經由前置放大器放大一定倍率，再由功率放大器作進一步的放大以及推動後級的輕載。在設計掌握被動匹配網路下，並搭配系統的PPM/OOK調變機制，可大幅提升操作效率。 可攜式核磁共振收發機系統主要用途在於分析氫原子，尤其是水含量多的地方，例如透視蠶繭、檢測蔬果的含水量、父母和胎兒互動以及居家自我檢測等應用，具有可攜性、低成本和簡易使用的特性，因此未來可以將此系統用於居家健康照護以提升全民生活健康品質。此系統的架構分為接收機、發射機、時序控制器以及0.5T強力磁鐵。 | zh_TW |
| dc.description.abstract | In recent years, the conscious of global people in the integration of medicine and electronic is arising, it makes many researchers in both field of electronic engineering and medical field cooperate frequently. It can be seen from the M2M workshop held by NTU-Intel, NTU medical electronics workshop and the course in NTU called Clinical Application of Medical Electronic Device which is a novel course in Taiwan. Therefore, following this trend, this paper will focus on biomedical electronic system and present two different applications ─ 'Integrated low-voltage transmitter' and 'Portable NMR transceiver.'
This Integrated low-voltage transmitter is implemented in TSMC CMOS Standard 0.18um process, and the transmitter contains the following circuit blocks ─ a voltage control oscillator, a pre-amplifier, a power amplifier and a matching network. Signal from voltage control oscillator will be amplified to certain amplitude and then will be transmitted to the antenna by the power amplifier. Under well-designed matching network and PPM/OOK modulation of whole system, the performance of this work is good. The main purpose of portable NMR system transceiver is to analyze the hydrogen atoms. Therefore, it is good for the places with rich water, such as perspective cocoon, testing the water content of fruits and vegetables, as well as parents and baby interactive applications and such as home self-testing. It has the feature of portability, low cost and ease to use. Thus, people can use this system for home health care to improve the national health quality of life in the future. The system architecture is divided into the receiver, transmitter, timing controller and 0.5T magnet. | en |
