中文摘要 | 本論文提出使用兩個電壓差動電流傳器,二個接地電容及二個電阻設計電壓式三輸入四輸出萬用二 階濾波電路。所提出的電路可實現電壓式三輸入、單輸出萬用濾波器或二輸入、四輸出多功能濾波器, 並具有以下之優點:在同一電路結構下可實現五種濾波信號,不需要任何的匹配條件及反相輸入電壓, 使用兩個接地電容有利於電路的積體化,並具有非常低的主動與被動靈敏度。最後,使用HSPICE 來驗證 電路之結果與理論可行性。 |
英文摘要 | A new universal voltage-mode biquadratic with three inputs and four outputs using two differential voltage current conveyors, two grounded capacitors and two resistors is proposed. The proposed configuration can be used as either a three-input single-output filter or two-input four-output filter. It offers the following advantageous features: simultaneous realization of voltage-mode low-pass, band-pass, high-pass, notch and all-pass filter responses from the same configuration; no requirement of critical component matching conditions; no requirement of inverting-type voltage input signal; employment of two grounded capacitors ideal for integration; low active and passive sensitivities. HSPICE simulation results confirm the theoretical analysis. |
