Özet
Six new second order band-pass filter configurations using only a single current-controlled current differencing buffered amplifier (CC-CDBA) are proposed. Further, the proposed filters also have a minimum number of external electronic components. They realize current-mode, voltage-mode and transadmittance-mode filter characteristics. The quality factor and natural frequency can be adjusted electronically without changing the values of the passive components. The proposed filters use a minimum number of passive elements (two or three). There is no second order active filter structure which uses two passive components and one active component in the literature. The validity of the proposed filters is verified through PSpice simulations. © Birkhäuser Boston 2008.
