脈波頻率調變升壓轉換器之設計與實現

近年來科技的迅速發展使得人們生活週遭充滿著各式各樣的電子產品，而追求產品的方便性一般會使用電池來供應產品電源，電池只能供應有限能量的情形下，因此有效的電源管理是很重要的。由於許多的電子產品會使用一次電池，而長久下來累積的廢電池所含金屬會對環境造成一定的影響，因此發明出充電電池取代一次電池，但於充電電池所能提供的電壓較低，可能造成產品誤動作或無法工作。而本論文針對以使用一次電池做為輸入電源的電子產品為例，如無線鍵盤、無線滑鼠、無線手把、簡報筆、遙控器與鬧鐘等，因更換充電電池所造成的供應電源過低而產品無法正常工作的問題，設計一個升壓轉換器電路，將充電電池1.2V電壓升壓至1.5V電壓，使原有電路可正常工作。論文中使用台灣積體電路製造公司所提供的 0.18μm 1P6M CMOS製程來設計所提出的脈波頻率調變升壓轉換器電路，可將1.2V輸入電壓轉換為1.5V輸出電壓，可供應的負載電流為1mA至50mA，其功率轉換效率為82.4%，輸出漣波電壓為16.19mV，綠性調節率為18.5mV/V，負載調節率為0.17mV/mA，所設計的晶片佈局面積為0.521mm2。

In recent years, the rapid development of science and technology makes people around full of life with a wide range of electronic products. The convenience of the pursuit of the product will generally use the battery to supply product power. The battery can only supply limited energy in the case, so effective power management is very important. Many electronic products will use a battery. Long-term accumulation of waste batteries contained in the metal will have a certain impact on the environment. So the invention of a rechargeable battery instead of a battery. But the rechargeable battery can provide a lower voltage, may cause the product malfunction or cannot work. This paper for the use of a battery as an input power of electronic products as an example. Such as wireless keyboard, wireless mouse, wireless handle, briefing pen, remote control and other electronic products. Because the replacement of the battery caused by the supply of power is too low and the product does not work properly. We designed a boost converter circuit. The rechargeable battery voltage of 1.2V up to 1.5V voltage. In this paper, we use the 0.18μm 1P6M CMOS process provided by Taiwan Semiconductor Manufacturing Company to design the proposed pulse frequency modulation boost converter circuit. It can let input voltage 1.2V to 1.4V converted to 1.5V output voltage. The load current can be supplied 1mA to 50mA. When the load current is 50mA, the power conversion efficiency is 82.4%, the output ripple voltage is 16.19mV and the linear regulation rate is 18.5mV/V. When the input voltage is changed from 1.2V to 1.4V and the load current changes from 1mA to 50mA its load regulation rate of 0.17mV/mA. The design of the chip layout area is 0.521mm2.
