Current‐mode dual‐output ICCII‐based tunable universal biquadratic filter with low‐input and high‐output impedances

A new tunable current-mode CM biquadratic filter with three inputs and three outputs using three dual-output inverting second-generation current conveyors, three grounded resistors and two grounded capacitors is proposed. The proposed circuit exhibits low-input impedance and high-output impedance which is important for easy cascading in the CM operations. It can realize lowpass, bandpass, highpass, bandreject and allpass biquadratic filtering responses from the same topology. The circuit permits orthogonal controllability of the quality factor Q and resonance angular frequency ωo, and no component matching conditions or inverting-type input current signals are imposed. All the passive and active sensitivities are low. Hspice simulation results are based on using TSMC 0.18µm 1P6M process complementary metal oxide semiconductor technology and supply voltages ±0.9V to verify the theoretical analysis.
