dc.description.abstract | 本論文提出一個超低功率單端石英振盪電路來減少功率消耗。此石英振盪電路包含單端啟動電路以及自充式架構,自充式架構取代傳統以放大器為基礎的架構,能適應性地對石英晶體充電,使得功率消耗由靜態功耗轉換成動態功耗而達到功耗減少的效果。自充式架構主要由邊緣萃取器以及脈波增壓器組成,透過重新利用石英晶體輸出的弦波產生狹窄的充電脈波去補償石英晶體內阻消耗的能量。所提出的32.768-kHz單端石英振盪電路使用0.18-μm CMOS製程製作,在0.25-V下整體電路的功率消耗為2.89 nW,核心電路佔據0.027 mm2。 | zh_TW |
dc.description.abstract | An ultra-low power one-pin crystal oscillator (XO), employing a one-pin startup and self-charged architecture, is proposed to reduce power consumption. The self-charge circuit, replacing a constant-current op amp, recharges crystal adaptively. It composed of start-up circuit, edge extractor and pulse booster. Self-charge method reuses crystal output sine wave to compensate for internal energy loss in crystal. The proposed 32.768-kHz one-pin XO, fabricated in a 0.18-μm CMOS technology, consumes 2.89 nW from a 0.25-V supply and the active area is 0.027 mm2. | en |
