摘要

本論文內容主要是設計一個脈波頻率調變升壓式的轉換器,其具有低工作電壓與零靜態電流消耗的特點。現今,體積小、重量輕、長待機時間正是電池操作之可攜式電子裝置的發展趨勢;針對於這些趨勢與發展,論文中提出一個低電壓與零靜態電流的電路技術,其不但可以降低工作電壓為一顆鎳氫電池的電壓(1.2伏特或1.5伏特),更可藉由零靜態電流的消耗之故,有效地延長可攜式電子裝置的待機時間。

此外,能隙參考電壓電路為轉換器中不可或缺的組成電路之ㄧ,其輸出參考電壓對溫度變化的抵抗能力,會直接影響轉換器輸出電壓的精確性;所以,一個具有新溫度補償機制的能隙參考電壓電路,亦在論文中被提出,其主要是利用一溫度補償產生器電路,針對不同的溫度區間加以補償,以提高輸出參考電壓對溫度變化的抵抗能力,進而提升轉換器輸出電壓的精確性。

本論文中的轉換器電路,是使用台灣積體電路製造股份有限公司所提供之0.35µm 2P4M 3.3V/5V 混合訊號互補金氧半導體製程來加以實現,整體晶片的面積為1.5×1.5mm²。

ABSTRACT

A PFM boost converter which has the advantages of the low supply voltage and zero quiescent current consumption is proposed in this thesis. Nowadays, the trends of the battery-operated portable electronic devices are small volume, light weight and long stand-by time. Due to these trends, a low voltage and zero quiescent current technique for the converter is needed. It not only can reduce the supply voltage to a single cell battery voltage, for example 1.2Volts or 1.5Volts, but also can extend the service time (stand-by time) of the portable electronic devices by the zero quiescent current consumption.

Besides, a bandgap reference circuit is an essential component of the converter. Because the output reference voltage is affected by the temperature variation, the precision of the output voltage of the converter will also be affected directly. Hence, a new bandgap reference circuit with a temperature compensation mechanism is proposed in this thesis. It mainly utilizes a temperature compensation generator to compensate the temperature variation of the output reference voltage in different temperature zones. Therefore, a higher precision output voltage of the converter which will be affected less by temperature variation can be obtained.

In this thesis, the converter is implemented by using the TSMC 0.35µm 2P4M 3.3V/5V CMOS process and the total chip area is 1.51.5mm².
