Abstract
This paper presents a current-tunable current-mode universal biquadratic filter with two inputs and two outputs using one modified current-controlled current differencing transconductance amplifier, two grounded capacitors and one grounded resistor. The proposed circuit provides following advantages: realization of low-pass, band-pass, high-pass, band-stop and all-pass current responses; orthogonal control of the natural frequency and the quality factor; employment of grounded passive components which is suitable for integrated circuit implementation and low active and passive sensitivities. Simulation results are given to confirm the presented theory.
