摘要: 在消費性電子產品蓬勃發展的今天,利用電池作為操作電壓源的可攜式電子產品對於減少功率消耗的需求與日俱增,進而需要一個有效率的電源管理系統以提供後端電路之所需。傳統的切換式穩壓器使用單一電感單一輸出的電路架構,在全整合的晶片系統中,會隨著後段電路個數的增加而使操作電壓源的個數也隨之增加,進而耗費多餘的被動元件與晶片面積導致的成本增加。 本論文主要介紹一個單一電感多輸出之穩壓器電路,採取電壓模式進行控制。利用功率分配控制系統所產生的時序,依序切換功率電晶體,使電路只需使用單一電感即可提供四個獨立的輸出電壓值,且同時具備了升壓與降壓的模式,使電路在應用層面上更具彈性。為了有效的縮減功率電晶體與補償電路外部元件的使用以減少成本上的支出,個別將第一與第三迴路的控制電路以一個比較器電路取代,使電路的複雜度與晶片面積降低,使此架構更適合用於整合系統晶片中。 本電路採用台積電(TSMC)的0.18um 1P6M CMOS製程來實現單一電感多輸出穩壓器的電路設計、模擬與佈局。其中,電路的工作電壓為1.8V,切換頻率訂定為2MHz,並使其依序產生四個獨立輸出電壓,其電壓值為2V、2.5V、1.5V、2.2V,所設計之穩壓器的最大轉換效率為83.76%,整體晶片面積為1.355*0.73mm2。
In recent years, the fast market growth of consumer electronics products requires, low power consumption for battery-operated portable devices. Thus, more and more effective power management systems for the circuits are needed. In the system on chip (SOC), traditional switching regulator architecture uses single-inductor single-output. However, each additional power supply of systems will consume more components and chip area to increase the cost. This thesis presents a single-inductor multi-output (SIMO) switching regulator circuit with the voltage mode controller. It utilizes the power-distributive control to switch the power MOS and uses only one inductor to provide four independent output voltages, both buck and boost mode, and makes this converter be used extensively. It reduces the use of power switches and external compensation components to decrease the cost, and uses only one comparator to replace traditional control circuit, which uses the first and third loops, separately. Hence, it reduces circuit complexity and die size. The proposed SIMO regulator was designed and fabricated in TSMC 0.18um 1P6M CMOS technology. Its input supply voltage is 1.8V and four outputs are specified at 2V, 2.5V, 1.5V, and 2.2V, respectively, with oscillator frequency at 2MHz. The maximum efficiency is 83.76%, and the chip area including I/O pad is 1.355*0.73mm2.
