| dc.description.abstract | 隨著電子生醫系統望微型化發展，裝置中能夠容納電池的空間大幅減少。由於電池尺寸的演進並不及半導體，導致單一裝置所能承載的電容量減少，進而縮短裝置使用壽命。有鑑於此，轉化周遭各式物理能量，諸如光能、熱能以及振動能等，的能源採集(energy harvesting)技術近年來受到廣泛的關注及研究。對於許多植入式生醫裝置而言，能源採集的可更新以及不虞匱乏等特性不啻為解決更換電池問題的一大福音。
以此為主題，本文提出一高效率壓電材料(piezoelectric material)能源採集介面電路作為起頭。將一般用於直流化交流電壓之全橋式整流器搭配上電感以及開關，即可大幅增加自壓電材料擷取出之能源量，而其技術需搭配之感測及控制電路僅需消耗小於一微瓦之功率。 接著，本文提出一兩級低輸入直流升壓電路(boost converter)用以處理由溫差發電材料(thermoelectric material)所供給之低電壓能量。藉由使用低閾值此電晶體以及本文所提出之設計原則，此升壓器可在無輔助(如輔助電壓、輔助震動等)的情況下將0.11伏特之電壓升壓至超越1伏，足供一低功耗生醫系統使用。 最後，本文提出一以溫差發電供能之無線心電監測系統暨心律不整偵測電路，藉以呈現能源採集介面電路的應用及整合潛力。 本文中所提出之電路均使用台積電0.18微米製程實現。 | zh_TW |
| dc.description.abstract | Owing to the shrink of biomedical electronic devices, the space permitted for battery is getting smaller and smaller, which results in the shortening of the device lifetime. As a promising solution, energy harvesting technique that scavenges power from ambient sources such as light, heat or vibration has been widely researched in recent years. Being renewable and inexhaustible, energy harvesting seems to be the best cure for the powering disease of the implant biomedical devices.
To begin with, a high efficiency piezoelectric energy harvesting interface is reported. With a company of an inductor and switches, the full-bridge rectifier can achieve a higher power extracting efficiency. The control overhead is much less than one micro watt. Following, we presented a two-stage low-input boost converter as a thermoelectric energy harvesting interface in Chapter 3. With low threshold voltage MOS transistors and the design guideline we proposed, the boost converter is able to boost a 0.11V voltage up to a level above 1V with extra assistance. The last work in this thesis is a thermo-powered wireless ECG monitoring system with arrhythmia detection circuit, which is a highly integrated biomedical system that shows the integration potential of the energy harvesting interface. All the works are fabricated in TSMC 0.18μm 1P6M process. | en |
