隨著生理遙測技術的進步，病人可以在日常生活不受干擾之下，讓醫護或是研究人員隨時監控並記錄活動中的生理參數。而這些生理遙測系統一般是利用紅外線或是無線電的方式來傳送這些生理參數。尤其是在設計可攜帶式的生理遙測系統時，必須考慮到體積、重量、方便性、耗電量和對生理訊號的即時處理能力等因素。

由於可供傳送和量測的生理參數種類相當多，因此本論文主要在於設計一個能夠讓病人輕便地攜帶在身上的無線心電圖的裝置。另外，藉由標準的CMOS 0.5μm 2P2M製程技術，將本裝置中基本的電路建構方塊-運算放大器電路製作成晶片，作為將本裝置整合在一顆晶片上的第一步。

With the progress of biotelemetry technique, the doctors and nurses or the researcher, can continuously monitor and record the physiological parameters in the activities of the patients who are not interfered in their daily life. The physiological parameters are always transmitted by using the infrared LED or RF in the biotelemetry system. But there are some factors such as size, weight, convenience, power dissipation and the real time processing of bio-signals must be considered especially when designing the portable biotelemetry system.

Therefore, this paper presents a wireless ECG device that is lightly and portable to the patients. Furthermore, the basic building block-operational amplifier in this device which is realized in one chip by using the standard CMOS 0.5μm 2P2M technology is the first step to integrate the device in one single chip.
