本論文的第一部分在設計生醫遙測系統，生醫遙測系統包含三部份，生醫感測器、前置放大器、無線通訊系統。生醫感測器和前置放大器設計和待測物有關，所以整個系統設計的重點在無線通訊系統。因為要容易能整合成單一晶片，我們不採用現有可用的通訊技術﹝無線網路或是藍芽技術﹞，而是自己設計無線通訊系統。我們所設計的無線通訊系統規格如下：操作頻率：2.4GHz-2.4835GHz ISM band、.傳輸距離：10公尺、.頻道數：40、調變方式：FSK。依據這些系統規格，我們採用了二次升頻發射機架構和超外差接收機架構，並訂出各個電路的參數，也利用ADS軟體去模擬整個系統，確認系統的可行性。
第二部份是實作，我們分為PCB和晶片來實作。在PCB方面，我們利用現有的晶片加上無線傳輸模組去製作無線心電圖，本文中有提到基本的心電圖量測方法，而此裝置只要將感測端換成其他感測器，就可用來設計出其他生醫訊號遙測裝置，像是無線PH感測器。在晶片方面，我們利用台積電0.25μm CMOS製程去設計接收端當中的LNA/Mixer，其模擬的電路特性有放大倍率為29db、雜訊指數為4.25db、1db壓縮點在-8dbm等等。
在台積電0.25μm CMOS製程已趨於準確以及穩定下，透過小心的設計及佈局，均可在2.4GHz得到不錯的電路特性，若是整合能再成功的話，單一晶片實現生醫訊號遙測系統晶片可快速達成，並且相信對人類的健康有著一定的貢獻

The first section of this thesis is to design a biotelemetry system. The biotelemetry system usually includes three parts: biosensor, preamplifier and wireless communication system. As we know the design of biosensor and preamplifier depends on what you want to measure, so the most importance of biotelemetry system is wireless communication system. In order to integrate the whole system in a chip easily, we don’t adopt any present wireless communication model, such as Bluetooth or WLAN. Otherwise, we design a simple wireless communication system for biotelemetry. The specifications of our designed system are: 1.Operating frequency: ISM band 2.4GHz-2.4835GHz, 2.Transmittion distance: 10meters, 3.Modulation type: FSK, 4.Channel number: 40. According to these specifications, adopted is two-step transmitter and super-heterodyne receiver structure, ADS software is used to simulate the system function.
The second section is implementation. We use two methods to implement the system, one is in PCB level, and the other is in IC level. In PCB level, we use limited IC and RF module to design wireless ECG measurement by the structure we mentioned before. We can replace other sensors to design another wireless XXX measurement, like wireless PH meter. In IC level, we design the LNA/Mixer chip of receiver by TSMC 0.25μm CMOS process. The specifications of LNA/Mixer we simulated is: Gain=29db, P1db=-8dbm, NF=4.25db.
The accuracy and stability of TSMC 0.25μm CMOS process now become better, so now we can design good performance chip at 2.4GHz by careful design and good layout technique. If the integration of IC can well done, our biotelemetry system chip will finished soon, in that day, our chip must provide contribution to people health.
