摘要

本論文使用五個第二代電流傳輸器(Second-generation Current Convyor，以下簡稱CCII)，實現單輸入三輸出之萬用二階巴特沃斯濾波電路設計。在不改變電路架構的情形下，實現輸出低通、帶通、高通、帶拒與全通五種濾波信號。
　　濾波電路設計部份，本論文使用二個第二代電流傳輸器，以及三個電阻與二個電容做為主體濾波電路之架構。再運用第二代電流傳輸器電流追隨的功能，以另外三個CCII分別做為擷取主體濾波電路中高通、低通、帶通濾波的輸出電流訊號。
本論文之電路以H-SPICE及TSMC 0.35um製程參數進行模擬驗證，設定操作頻率在1MHz。對電路進行頻率響應精準度、穩定度、敏感度、蒙地卡羅模擬、動態範圍、線性範圍以及交互調變頻譜等模擬，其模擬輸出結果具有二階萬用濾波器之特性。

In this paper, we proposed a universal current-mode biquad of the Butterworth filter with one input and three outputs using five CCIIs. The prosoned circuits can simultaneously realize high-pass, low-pass, band-pass, all-pass and band-reject signals form the same configuration.
In the filter circuit part, this paper uses two second-generation current conveyors, three resistors and two capacitors to be a main structure of the filter circuit, based on the current follow function of the second-generation current conveyor, additional three CCIIs were intercepted signal by low-pass, band -pass and high-pass .
In this paper, the sofeware H-SPICE with TSMC 0.35um process parameter was used for simulation and verification. To set the operating frequency at 1MHz to verify the frequency response, stability, sensitivity, Monte Carlo simulation, dynamic range, linearity and spectral modulation, based on the above simulation process to verify the output with the characteristic of the universal biquadratic filter .
