在現代高度科技化的社會當中，眾多電子產品藉由感測器來拓展應用領域，若能將其鏈結環境監控與居家照護、防災，更能將科技融入生活，成為智慧生活的核心技術之一。
本論文提出一可應用於獵取光伏能源之切換式升壓型轉換器，可提供電能給諸如溫度等諸多感測器，其控制技術係採用自適性導通時間控制，使系統即便操作在極輕負載條件下仍具有較高的整體能量轉換效率，達到脈波頻率調變之特性
，且在輸入電壓的變動下，亦可降低系統切換頻率之變異量；此外，另加入一零電流切換調整機制，不僅能避免因同步整流而產生的功率損耗，更可再進一步提升整體能量轉換效率。
本次設計晶片係使用TSMC 0.18-μm CMOS標準製程來實現，整體晶片佈局面積為1.053×0.603 mm2 (含I/O pads)，其輸入電壓範圍可操作於0.8V~1.2V，輸出電壓則可藉由內建之帶差參考電路將其穩定在1.8V，其後模擬結果顯示，最大輸出電壓之漣波大小約為2%，並具有超廣域之負載電流範圍(30μA~30mA)，其中在負載電流為5mA時，可達最高能量轉換效率86.45%。

Sensors play a dominate role in environmental monitoring, disaster prevetion, home care … and so forth to realize the so-called intelligent living for modern humankinds. How to power such immense sensors becomes an everlasting hot topic for related research.
In this thesis, a boost converter for on-chip solar cell is proposed to power the succeeding temperature sensor. The adaptive on-time control is adopted to increase the power conversion efficiency under extreme light load and narrow the switching frequency range under input voltage variation. The zero-current switching is also applied to reduce the power loss caused by reverse recovery current to further enhance the overall conversion efficiency.
The chip is realized in a TSMC 0.18-μm standard CMOS process with 1.053×0.603 mm2 chip area (including I/O pads). The operational input voltage range is 0.8V~1.2V and the output voltage is stabilized at 1.8V. With post-simulations, the output ripple is around 2% under an extremely wide load current range of 30μA~30mA. The peak power conversion efficiency is 86.45% at 5mA load current.
