在近年來人們開始提倡綠能發展，除了增加再生能源的利用之外，能源回收
也是一直是被大家所廣泛討論的課題。而在現今的社會，與過去不同的是，可攜
式電子產品近年來發展快速，現在幾乎人手至少一台可攜式電子產品，無論是智
慧型手機、平板電腦或是數位相機等，若把所有人在可攜式電子產品上的耗能加
總，其值是非常驚人的。為了解決此問題，本篇論文提出一種利用可攜式發電機
對手機電池充電的想法，目的是要利用可攜式發電機產生能量，提供電子產品做
充電使用，而在可攜式發電機與電子產品之間就需要一個電壓調整器來穩壓。本
研究即提出一個無輸出電容式低壓降電壓調整器，其不僅擁有較小的晶片面積以
及消耗功率外，而且在不需要輸出電容的情形下，能有穩定的輸出電壓且容易與
前後端電路做整合，增進了使用的便利性。
此晶片所採用的是TSMC 0.35μm 2P4M CMOS 製程來實現，在輸入電壓6V
的情形下，輸出電壓為5V，滿載電流約為300mA，晶片面積大小為1.013 
1.013mm2，可在無輸出電容的情形下有穩定輸出電壓。
