    • 本論文中，我們利用低電壓電路設計方式，實現一名為語意修辭模糊邏輯控制器的新型模糊邏輯控制器。在電路實現方面，採用混合訊號電路和管線式時脈的設計方法。系統中之訊號處理單元以電流式電路實現，不但可以簡化電路的複雜度，更易於低電壓電路設計。
    為了達到低電壓之目的，本論文採用兩種低電壓電路設計之技術：wide-swing及level-shifter技術。wide-swing技術提供較高的準確度；level-shifter技術適合於低電壓之應用。由此，我們設計許多低電壓電路，例如最大電流選擇器、最小電流選擇器、平方電路及平方根電路，並據以實現一低電壓操作之語意修辭模糊邏輯控制器。
    本設計所需之電源供應電壓為1.5V，總功率消耗為18mW。模擬結果顯示此語意修辭模糊邏輯控制器之正確性。

    In this thesis, we use low voltage circuit design technique to implement a novel fuzzy logic controller called linguistic hedge fuzzy logic controller. This design is based on a mixed-signal circuit design with pipelined strategy. A current-mode approach is adopted in the signal processing unit, thus not only circuit complexity can be reduced but supply voltage can be decreased.
    Two low-voltage techniques are considered, they are wide-swing technique and level-shifter technique. The wide-swing technique provides a high accuracy; the level-shifter technique is suitable for low-voltage applications. We design several low-voltage circuits such as maximum current selector, minimum current selector, squarer/divider circuit, and square-rooter/multiplier circuit. Finally, a low-voltage linguistic hedge fuzzy logic controller is implemented.
    The supply voltage of this design is 1.5 V. The power consumption is 18 mW. Simulation results demonstrate the LHFLC performs well.
