Abstract
This paper presents a new electronically tunable current-mode multifunction biquadratic filter using a new active building block called the multiple-Z with controlled current gain current-controlled current conveyor transconductance amplifier (MZCG-CCCCTA). The proposed filter employs only one MZCG-CCCCTA and two grounded capacitors which offers the following attractive features: realization of low-pass, band-pass, high-pass, band-stop and all-pass current responses from the same configuration; independent current control of the natural frequency (ωo) and the quality factor (Q); employment of only grounded capacitors which is suitable for integrated circuit implementation; employment of the minimum active and passive components; no requirement of component-matching conditions; low active and passive sensitivities. The characteristics of the proposed circuit are simulated using PSPICE to confirm the theory. © 2012 IEEE.
