本論文提出一個可隨輸入電壓變化自我調整輸出降-升壓型態之單電感雙輸出直流直流轉換器，隨輸入電壓變化調整降-升壓或升-升型態，擁有更少的功率開關與外部補償元件。採用電壓模式控制提昇系統的抗雜訊能力，第一組輸出以電壓比較器取代輸出誤差放大器可獲得快速的反應時間，並且只需一組補償器，更適合於SoC的應用，並加入基體偏壓電路防止系統額外漏電流。這個轉換器以TSMC 0.18um 1P6M CMOS製程設計與製造。在輸入電壓範圍變動下，第一組受比較器控制的輸出可降壓或升壓，第二組輸出為升壓，最高效率為92％。

This paper presents A single-inductor dual output DC-DC converter with output self calibration technique controlled by different input voltage. It can operated in buck-boost mode or boost-boost mode according to input voltage varied. The system uses fewer power switches/external compensation components to reduce cost. This converter works under voltage mode control to have better noise immunity. The first output control by comparator to replace error amplifier which has the fast response time, and only a compensator, is more suitable for SoC applications. The system with body bias circuit to prevent leakage current. The proposed SIDO converter was fabricated in TSMC 0.18μm 1P6M CMOS technology with input supply voltage 1.6-3.3 V. The first output VO1 can operates either at buck mode or boost mode , while the second output VO2 can only operates at boost mode .
