摘要

無線感測器網路的應用在過去幾年來已經廣泛的被討論，例如環境的監控、醫療照顧、重大災害偵測，隨著科技、積體電路、微機電與無線通訊的進步，許多應用已經可以在現今生活中實現出來。
我們使用台積電2P4M 0.35um 標準CMOS 製程來實現我們所設計之感測器晶片，首先我們先製作了一個433MHz 的頻率合成器，作為之後的無線通訊系統的發送機，接著製作一個具有無線傳輸的感測器，其內部電路包含溫度感測器、類比數位轉換器及OOK 發送機，也是由CMOS 製程製作出來，另外由一組OOK 接收器接收資料。
另外，核磁共振照影，是近年來在臨床診斷上相當重要的影像工具，此種準確而不必侵入人體的方法為人體內部器官造影，對醫學的診斷很有幫助。所以我們做了部份的研究，關於加速核磁共振平行化的成像，分別用商業IC 元件與台積電2P4M 0.35um 標準CMOS 製程製作了兩種低阻抗前置放大器。

The applications for wireless sensor networks (WSN) have been extensively claimed in the past years, such as environmental monitoring, healthcare and calamity detection. Due to the technical advances of integrated circuit, micro-electromechanical systems and wireless communication, several applications become more feasible
nowadays.
We achieved the wireless sensing circuit by TSMC 2P4M 0.35um standard CMOS process. Firstly, a 433MHz frequency synthesizer used as the transmitter of wireless
communication system is designed. Then, a wireless sensor circuit composed of temperature sensor, analog-to-digital converter and OOK transmitter is also fabricated in CMOS process. Another OOK receiver is utilized to receive the data in the experiment.
Moreover, magnetic resonance imaging is an important tool in clinical diagnosis because of its imaging method without invading the human body. This is useful for the
medical diagnosis. Therefore, we also do parts research about speeding up parallel imaging of MRI. We also design two different low input impedance preamplifiers using
commercial IC and TSMC 2P4M 0.35um standard CMOS process respectively.
