中文摘要 | 本文旨在提出兩個新型電壓模式泛用二階濾波 器,每個濾、波器由兩個正型FTFN戶符合成。所提出的 電路可以合成二階高通,帶通,低通,帶才巨及全通濾 波器。電路的主動及被動靈敏度皆低,只使用正型的 FTFN元件簡化了線路。電腦模擬驗證了理論的正 確。 |
英文摘要 | Two voltage-mode universal biquadratic filters usìng positive four-termina1 floating nullors (PFTFNs) are presented. Each one of the proposed filters using two PFTFNs. The proposed configurations can realize lowpass, bandpass, highpass, notch and allpass transfer functions. Moreover, the proposed circuits enjoys low active and passive sensitivitily. The use of only positive FTFNs simplifies the configurations. Simulation results are given to verify the theoretical analysis. |
