วงจรกรองความถี่โหมดแรงดันหลายหนาที่โดยใช CCCIIs Voltage-mode universal filter based on CCCIIs

This article presents a voltage-mode universal biquadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, Second generation current controlled current conveyors (CCCIIs). The features of the circuit are that: the quality factor and pole frequency can be tuned independently via the input bias currents: the circuit description is very simple, consisting of merely 3 CCCIIs and 2 capacitors. Without any external resistors and require component matching conditions, the proposed circuit is very appropriate to further develop into an integrated circuit. The PSPICE simulation results are depicted. The given results agree well with the theoretical anticipation.
