Abstract: | 本論文中提出了一個單電感雙輸出直流轉直流降壓併升壓轉換器。功率級開關的切換序列有別於傳統單電感雙輸出轉換器,除了三個開關外再加上飛輪(free-wheeling)開關用以防止電感電流逆流導致轉換器整體效能下降。控制迴路方面採用漣波控制機制,因此能提高整體開關的切換頻率進而縮小被動元件的體積,對於未來電源應用在整合電路上有相當的幫助。
此晶片使用台積電0.18微米互補式金氧半製程實現。在1.2伏特的供應電源下,可提供0.95伏特的壓降電壓及1.4伏特的壓升電壓,模擬之能源轉換效率可達80%。 A Single-Inductor Dual-Output (SIDO) DC to DC Buck/Boost Converter topology is proposed. The power stage switching sequence is different from conventional type. In addition to three switches, a freewheel switch is used to prevent negative inductor current occurring and degrading the power efficiency. The converter uses ripple-based control method, which facilitates high switching frequency and decreasing the passive components volume. The chip is fabricated in 0.18 μm CMOS, the proposed SIDO DC-DC Buck/Boost Converter can produce 0.95 V buck voltage with 1.4 V boost voltage. The power transfer efficiency could reach 80% in simulation. |
