摘要

本論文嘗試使用超大型積體電路設計方式，來設計混合式燃料電池系統電源管理電路，並且針對給現在攜帶型設備。我們使用燃料電池作為主要供應電源，鋰電池則作為備用電源，此電路結合兩種電源供應，並且設計電路來管理整個系統，使用HSPICE做模擬，製程使用TSMC 0.35μm 2P4M 5V CMOS製程。根據模擬結果，最大輸出平均電流為232mA，最小輸出平均電流為149mA，電路輸入電壓範圍是3.87V到5V之間，輸出電壓在3.6V到3.64V之間，總電晶體數為83，晶片面積大小1.58mm×1.25mm，當負載20pF，消耗功率是1.51W。

In this thesis, we propose a micro fuel cell power management circuit for portable devices. We use fuel cells for our main power supply and a lithium-ion battery for its backup power. This circuit combines two power sources and manages the whole power system. The whole circuit has been approved by HSPICE with TSMC 0.35μm 2P4M 5V CMOS process. According to the simulation results, the circuit provides the maximum output current of 232mA and the minimum output current of 149mA. The input voltage range is 3.87V-5V. The output voltage range is 3.6V-3.64V. The total number of transistors is 83. The size of chip is 1.58mm×1.25mm. The power consumption is 1.51W when load is 20pF.
