以第二代電流傳輸器設計三入單出的萬用二階電壓式濾波電路

本研究主要實現二階低通、帶通、高通、帶拒與全通萬用濾波電路。類比濾波器是以簡化電路和精準的輸出信號為設計優先，因此本研究以此為目標而提出的設計法，先將二階低通、帶通、高通、帶拒與全通濾波電路的轉移函數以矩陣模式表示，並使用主動元件(CCII)特性完成矩陣關係式。電路中的主動元件主要採用兩種特別的電流式主動元件：第二代電流傳輸器(Second-generation Current Conveyor; CCII) ，可實現三輸入一輸出，在電路設計過程中使用兩個主動元件、一個浮接電容、一個接地電容、兩個浮接電阻一個接地電阻，以完成最精簡之電路。設計完成的電路以1000kHz 為操作頻率，並以電路模擬軟HSpice 使用 TSMC035μm 製程進行電路模擬與驗證，探討電路輸出信號不準確的因素，最後利用被動元件對頻率響應及敏感度分析與蒙地卡羅分析、穩定度做深入研究，將被動元件值進行理論合適調整並改善誤差。

In this study, the main achievement of Universal biquadratic filter circuit. Analog filter circuit is simplified and accurate output signals for the design considerations, this study as a goal of the proposed design method, the first Universal biquadratic filter circuit matrix model representation and use initiative to complete the matrix element characteristic relationship. The main active components in the circuit uses second-generation current conveyors , the use of two active components in the circuit design process, one grounded capacitance, one floating capacitance ,two floating resistance and one ground resistance, to complete the most simple circuit. The circuit design is completed for the operating frequency of 100kHz and Hspice software uses TSMC035μm process for circuit simulation, and discuss circuit output signal is not precise factorsFinally, the sensitivity of the frequency response of passive components analysis and Monte Carlo analysis to in-depth research.
