摘要

本論文以單一個第二代電流傳輸器主動元件(Second-generation Current Conveyor，簡稱CCII),搭配四個電阻、兩個接地電容並且特別讓其中一個電阻與電容做RC串聯設計來設計單輸入單輸出的第二代電流傳輸器主動電流式濾波器電路，來實現全通濾波訊號、帶通濾波訊號、帶拒濾波訊號。
這次的電路設計是以電壓式Sallen-Key電路設計為參考，並並設計成電流式的Sallen-Key電路在運用節點分析法完成其矩陣關係式後，在利用克拉瑪公式推導出理想的二階轉移函數完成本次的電路設計。
本文所設計的電路使用H-SPICE配合TSMC 0.35um製程參數，並以1MHz為操作頻率進行模擬與理論驗證,並分別做了頻率響應、蒙地卡羅、雜訊與功率消耗、穩定度、敏感度、動態範圍、交互調變平譜等模擬利用這些模擬驗證了本論文所設計的電路運用了RC串聯設計在輸出上仍然保有二階濾波器的特性並趨於精準。

This paper adopts single CCII(Second-generation Current Conveyor) is an active element , used four resistors and two grounded capacitors among cascades of one resistor and one capacitor especially, In this paper, design CCII(Second-generation Current Conveyor)using one input and one output filter, to achieve full(All-pass)filter signal丶bandpass(Band-Pass) filter signals丶Notch filter signals.
In this paper, after the most simplified circuit design as the goal, and the use of nodal analysis method to complete its matrix of relationships in the use of Cramer’s rule was deduced second order transfer function over the completion of the circuit design.
This article is designed to use H-SPICE circuit with TSMC 0.35UM process parameters, and to 1MHz operating frequency of the simulation and theoretical verification. Respectively using that Frequency Response丶Monte Carlo Method丶Noise丶Power Dissipation丶Stability丶 Sensitivity Using these simulations in this paper the design of circuits using RC series design retains characteristics of second-order filter at the output and tend to be accurate.
