摘要 本論文與過往學者發表的論文皆是單輸入三輸出電壓式多功能(低通、高通、帶通)濾波電路,其中有兩位學者皆使用五個電流傳輸器,兩個電容,並使用六個或七個電阻,而其中有位學者使用了4個電流傳輸器,五個電容及三個電阻,而本論文僅使用二個電流傳輸器,兩個電容及三個電阻即可設計出多功能,此電路設計主要目的即為簡化電路,並探討輸出信號進行驗證。 此電路所使用了最少的被動元件,在IC下線中可以有效的減少面積,並且將電容進行接地也減少的寄生效應,所以也有著低敏感度特性,並且響應也來自同一個裝置,也不需要關鍵的匹配條件。 本文之電路均以電路模擬軟體H-SPICE進行製程的模擬與論點驗證,並使用製程參數為TSMC 0.35um進行模擬。
Abstract Abstract-Avoltage-mode low-pass, band-pass, and high-pass filter with single inpit and three output, employing only two compound current conveyors, two grounded capactiors, and three resistors, is proposed. The proposed circuit offers the following advantageous features: realization of voltage-mode low-pass, band-pass, and high-pass filter responses from the same configuration: no requirement of critical component matching conditions; employment of ground capacitors ideal for integration; low sensitivity characteristics; and simpler configuration due to the use of only two compound current conveyors. Degree in accuracy, stability circuit, sensitivity, Monte Carlo, dynamic range and linearity, and other interactive modulation spectrum characteristics of the circuit using the TSMC 3.3-V 0.35-μm CMOS process parameters characteristic of the circuit simulation.
