摘要

本論文主要實現高頻(1MHz)二階含有低通、高通、帶通的巴特沃茲(Butterworth)濾波電路。研究討論電路的可行性，分成電容都在迴路上(FEEDBACK LOOP)，電阻在迴路上及混和型三種作為電路比較。電路中的主動元件採用運算轉組放大器(Operational Trans-Resistance Amplifier，簡稱OTRA)。最後完成設計的電路，採用三個主動元件、六個電組及兩個電容。
設計電路以1M(Hz)為主要操作頻率，並改變操作頻率，比較高頻與低頻時三種電路輸出優劣。本電路模擬軟體H-Spice使用TSMC035 μm 製程進行電路模擬，利用MATLAB模擬理論圖形與數據，再與實際電路比較差異。接著考慮主動元件非理想效應的輸出信號，再將電路操作於其它頻率，並探討電容與電阻寄生效應相互關係，與其影響輸出信號的因素，然後利用被動元件對頻率響應的敏感度分析做深入研究。

This thesis presents a new second-order Butterworth Filter using the
operational transresistance amplifier (OTRA) as the active component.
And achieve Low-pass High-pass and Band-pass for Butterworth Filter.
Discuss the feasibility of the circuit , The capacitance in Feedback ,
not in Feedback and complex. This Filter is composed of three OTRAs
and six resistors and two capacitors.
Design to the main operating frequency for 1MHz, and change to
operating frequency, the software H-Spice simulation used TSMC035
μm process and using MATLAB simulation, then compared with the
difference the actual circuit. Then consider the non-ideal effects of
active element output signal , and to explore the parasitic capacitance
and the resistance relationship the output signal and its factors and the
use of the frequency response of passive components study of the
sensitivity analysis .
