Abstract

伴隨科技日新月異，可攜性裝置的需求量與日俱增，而提供可攜式裝置的能量來源 就變成非常的重要，如何能讓此能量來源能永續的產生，將成為一個重要的課題，微機 電系統是一種能把自然界的能量轉換成電能的系統，並且擁有非常理想的可攜性，所以 我們的研究將提出一個智慧型的直流電源轉換電路，把電源管理理論實現於此永續操作 的微機電系統中，使得此系統能夠在最有效率的情況下從外界綠色能源中得到一個穩定 的電源供應。並且我們可以使用整流器(rectifier)和直流-直流電源轉換器(DC-DC converter)有效率地轉換出所需要的穩定輸出電壓。 而此計畫的重點乃透過手機電池的電壓來提供手機相機變焦所需的驅動電壓，並且 有鑑於電池的壽命有限，因此電源管理成為在功率消耗中最常探討的因素。另外，由於 的科技發展，現在手機的普及率已經相當驚人，並且在功能的需求上也是日益增加。因 此，在科技整合的趨勢潮流下，手機的功能也越來越多，手機搭配數位相機已是成為最 基本的配備，所以我們提出了”創新異質整合智慧型手機相機模組之研究”，從根本的 問題的地方著手，利用液晶鏡頭與傳統透鏡鏡頭相互結合、搭配的方式，能使手機厚度 更加縮小，但不失變焦的功能，也可以有更低的功率消耗，讓手機的待機時間可以更久。

The technology is changes with each passing day. The requirements of potable device are grow with each passing day. Wireless communication and potable devices are popular in today’s technology. Low power designs become more and more important. Owing to the growth of low power designs, we even can use the ambient energy sources for our system. As we know, it is so-called green energy. It also means that this system is a self-sustention operating system using green energy as energy source. Thus, how to convert and manage this tiny energy becomes a major topic in this system’s design. Our research aims at a smart DC-DC converter and adapts a suitable power management theory in the self-sustention system. Based on this architecture, this self-sustention can get stable supply energy under the optimal energy transferring efficiency. We can use rectifier and DC-DC converter efficiently convert the unstable voltage to a specified and stable output voltage. The key point of this project is to supply the driving energy of zooming of the cell phone camera. Owing to the life time of camera battery is finite, power management becomes the most important issue of power dissipation. Besides, due to the development of technology, cell phone has become very popular The function requirements are also increasing each passing day. Therefore, under the trend of technology combination, the functions of cell phone become more and more. And the combination of digital camera and cell phone is the most basic equipment. We proposes a “The study of a novel heterogeneous integrated compact camera module” to solve the cardinal problem. We integrated LC lens and conventional lens together to make the size of zooming mechanism smaller without losing the function of zooming. This kind of technique not only provides low power consumption but also extends the standby time of cell phone.
