摘要

本論文主要使用單一個第二代電流傳輸器設計萬用主動電流式濾波器電路類比濾波器是以簡化電路和精準的輸出信號為設計考量，故本研究以此為目標而提出的設計方法，先將二階萬用濾波器的轉移函數以矩陣模式表示，並使用主動元件特性完成矩陣關係式。
　　電路中的主動元件使用特別的電流式主動元件:第二代電流傳輸器(Second-generation Current Conveyor，簡稱CCII)，在電路設計的過程中總共使用了一個主動元件、兩個串接電容與三個串接電阻、一個接地電容與兩個接地電阻，已完成最簡電路。
　　本論文設計之電路將以1MHz為操作頻率，使用HSPICE及TSMC-0.35um製程參數進行9種不同的模擬，測量頻率響應、功率損耗、蒙地卡羅、敏感度、穩定度、線性與動態範圍、交互調變頻率，觀察模擬結果與理論驗證。最後，將本論文設計出的電路，利用論文內的數據資料，將其下線成實體之電路並在未來應用在實務之上。

In this thesis, using the second-generation current conveyor current formula to achieve universal active filter circuit. Analog filter circuit is simplified and accurate output signal design considerations, so the research objectives in this design method is proposed, the transfer function of the first second-order universal filter matrix model representation, and using an active element characteristics completion matrix relationship.
　　Active circuit element using a special current type active element: a second-generation current conveyor (Second-generation Current Conveyor, referred CCII), the circuit design process uses a total of active components, two capacitors connected in series and Three a series resistor, a capacitor to ground and two ground resistance, has completed the most simple circuit.
　　In this paper, the design of the circuit will be 1MHz operating frequency, use HSPICE and TSMC 0.35um process parameters 9 different analog measuring frequency response, power loss, Monte Carlo, sensitivity, stability, linearity and dynamic range, interactive modulation frequency, observe the simulation results and theoretical verification. Finally, this paper design a circuit using the data within the paper, which was offline circuit entities and future applications in the above practices.
