Abstract :
This article presents a current-mode universal biquadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, based-on current controlled current differencing buffered amplifiers (CCCDBAs). The features of the circuit are that: the quality factor and pole frequency can be tuned orthogonally via the input bias currents: the circuit description is very simple, consisting of merely 3 CCCDBAs and 2 grounded capacitors. Without any external resistors and using only grounded elements, the proposed circuit is very comfortable to further develop into an integrated circuit. The PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation. The maximum useful frequency range is up to several hundred megahertz, where the power consumption is approximately 2.4mW at plusmn1V power supply voltages
